This model of a bacterial sodium channel shows the pore domain of the protein. The pore domain is a homo-tetramer in which 4 identical proteins come together to form the ion pore — exposed on the outside surface of the cell. The protein structure was captured in its open conformation, where your students can easily see how hydrated Na+ ions can be released into the cytoplasm after passing through the pore. Voltage-gated sodium channels play a critical role in generating the action potential in signaling neurons. As they open — in response to a stimulus — sodium ions enter the cell, leading to depolarization and a propagation of the action potential.

Also see Water Kit© and NaCl Lattice© (page 3).

Sodium Channel Mini Model

Potassium Channel Mini Model

3.75” Plaster Model $95 (SCMM)

The potassium channel is a 4-subunit, transmembrane protein that allows the rapid passage of potassium ions — but not sodium ions — across the membrane. The protein backbones of the 4 subunits come together to form a channel, with carbonyl oxygen atoms precisely positioned in 3-D space to replace the water that normally hydrates each ion. Since there is no energetic diff erence between a hydrated potassium ion and the same ion bound in the pore of the potassium channel, the ion rapidly passes through the channel in a frictionless manner. 3.75” Plaster Model $78 (PCMM)

Also see NaCl Lattice© (page 3).

Potassium Channel Bound with Scorpion Toxin Mini ModelThese 2 models enable you to tell many stories. The green potassium channel model illustrates how this amazing protein allows the rapid transport of potassium channel ions while simultaneously preventing the fl ow of smaller sodium ions. The yellow scorpion toxin model (from the Chinese scorpion Buthus martensi) shows how disulfi de bonds stabilize the structure of this small protein, how some proteins interact to form multi-protein complexes, and how a strategically placed lysine side chain of the magnet-docked scorpion toxin plugs the channel through which potassium ions normally fl ow. The model also displays additional amino acid side chains that are important in stabilizing the interaction between these 2 proteins.5'' Plaster Model $87 (PCSMM)

Mini models are made of plaster by 3-D printing and should be handled with care. Models will break if dropped, held tightly or handled roughly.

Channel Protein Mini Models

Aquaporin Channel Mini Model

The Aquaporin Mini Model opens to show water molecules rolling over in their passage through the channel.

Aquaporin — a membrane-spanning protein — is responsible for moving water across a lipid bilayer. Its structure consists of 6 alpha helices and 2 half alpha helices that form an hourglass shape through which water molecules move one at a time. Two asparagine amino acids are strategically positioned near the center of the hourglass and provide selectivity to this channel, allowing only water molecules pass through. 3.75” Plaster Model $77 (ACMM)

Also see Water Kit© (page 3).

Channel protein mini models are built at the same scale.

β-Globin Folding Kit©

Proteins become real in your students’ hands as they fold 3 mini toober β-globin fragments and discover the primary, secondary and tertiary structure in this model. Maps guide your students in folding the mini toobers into β-globin’s 3-D shape. Use the folded mini toober model of β-globin to discuss protein structure, the important role of hemoglobin in oxygen transport and the lasting eff ects of a single amino acid mutation on a protein. The kit includes mini toobers, folding map guides, amino acid side chains, heme group, iron atom, oxygen atoms and an assortment of parts to mark and connect the fragments. Teacher notes and student handouts are available online. The folding kit can be used successfully by 6 to 9 students working in 3 teams. Folding Kit $118 (BGFK)

Amino Acid Starter Kit©

Your students will explore the primary, secondary and tertiary structure of proteins with this captivating kit. They will learn the chemical properties of the 20 amino acid side chains through a dual coloring scheme — a colored clip at the base of each side chain indicates chemical properties while embedded colored balls in side chain models show atomic structure. Understanding protein structure begins with this unique combination of atomic and chemical properties of the amino acids. Through the kit’s engaging, hands-on activities your students will gain a basic knowledge of protein folding before discovering the importance of secondary structure and active sites with additional folding activities.

Each 1-group set includes 1 chemical properties circle, 1 amino acid side chain list, 22 amino acids, 1 4-foot mini toober, 15 plastic clips and 6 hydrogen bond connectors. Multiply each item by 3, 5 or 6 for the 3-group, 5-group and 6-group sets. Teacher notes, student handouts and interactive Jmol visualization tools are available online.

CRISPR/Cas9 Mini Model

DNA Mini ModelThis model immediately engages your students in thinking about the structure of DNA. You can guide a discussion of the nature of models — and the usefulness of multiple representations of any molecular structure. The DNA Mini Model represents the classic DNA double helix in 4 formats. The bottom section of the model shows a surface format emphasizing major and minor grooves. Moving up, all atoms are in a CPK colored spacefi lled format. The next section shows the 4 nitrogenous bases in a CPK wireframe format. In the top section of the model, each of the 4 bases is colored with a solid color.

Give your students a hands-on exploration of the next generation in genetic engineering! We are thrilled to be able to off er an aff ordable version of the 3D-printed Cas9 component of the CRISPR gene editing technology. Jennifer Doudna, PhD, Professor at UC-Berkeley and Executive Director of the Innovative Genomics Initiative (IGI), is one of the pioneers of the CRISPR/Cas9 technique, which allows researchers to make specifi c changes to the genetic code of cells and organisms. 3D Molecular Designs designed and built the model for Dr. Doudna with Jacob Corn, PhD, Scientifi c Director of the IGI. The front segment detaches from the model, allowing students a closer look at the guide RNA and two strands of DNA inside.

Water can exist in any one of three states — a gas, liquid or solid (ice). At 0o C (32o Fahrenheit) the thermal motion of the water molecules slows to the point that stable hydrogen bonds form between the molecules and an ice lattice forms. Ice �oats since ice lattices are less dense than liquid water. This causes lakes to freeze from the top down, insulating the life beneath. Water molecules can form more than a dozen crystalline structures depending on temperature and pressure; however, nearly all ice on the Earth's surface and in its atmosphere is a hexagonal phase denoted as ice Ih.

DNA is a long, linear polymer of four di�erent nucleotides — adenine, thymine, guanine and cytosine (A,T,G,C). The sequence of these four nucleotides in your DNA speci�es the sequence of amino acids in your proteins. Your DNA exists as a double helix. Two complementary strands of DNA wrap around each other to form a right-handed double helix. This double helix contains complementary A-T and G-C base pairs. In 2001, researchers determined the exact nucleotide sequence of the 3.2 billion base pairs of the human genome.

Phospholipid bilayers form cell membranes to separate

the inside of your cells from the outside. The hydrophobic nature

of a phospholipid bilayer prevents the free movement of most small

molecules into and out of your cells. Proteins embedded in cell membranes

allow ions and small molecules to pass through the membrane. Each protein has a

speci�c shape that allows it to pass a speci�c molecule — such as water — into or out of the cell.

Plants use glucose units to build two di�erent linear polymers — either starch or cellulose. You, as a human

being, have an enzyme (protein) that cuts o� the individual glucose units of starch — but not cellulose — so that glucose

can be oxidized to release its energy. When you eat a meal, some of the glucose is stored in a branched polymer called

glycogen. Glycogen rapidly releases glucose to provide energy between meals.

Nucleotides are the building blocks of your DNA and RNA. There are four nucleotides in DNA, each composed of a base — adenine (A), thymine (T), guanine (G) or cytosine (C) — a

deoxyribose sugar, and a phosphate group. In RNA, the deoxyribose is replaced by ribose, and the thymine base is replaced by uracil. In both DNA and RNA, enzymes called polymerases join the monomer nucleotides together to make long polymers. Cells use the unique sequence of nucleotides in DNA as a code

to build the correct sequence of amino acids in a protein.

Carbohydrates — also called sugars — are energy-rich molecules that provide fuel for your body. Glucose is a carbohydrate that plants build from carbon dioxide and energy from the sun in a process called photosynthesis. The energy stored in carbohydrates is released when organisms break down food during cellular respiration. This energy is captured as ATP and used to power life processes.

Phospholipids are unusual molecules with two distinct properties. One portion of the molecule is a long water-avoiding (hydrophobic) carbon tail. The other portion is a water-seeking (hydrophilic) phosphate group. In your cells, phospholipid molecules spontaneously assemble into a lipid bilayer with the hydrophobic carbon tails buried and hidden from the polar water molecules. The polar phosphate portion of the phospholipids are on the surface, exposed to water.

PROTEINSYour body produces approximately 50,000 di�erent proteins, each with a speci�c shape that allows it to perform a speci�c function. Aquaporins are channel proteins that facilitate the selective di�usion of water in single �le across a cell membrane. Thirteen variants of aquaporin have been identi�ed in humans. Each is composed of 250-300 amino acids. Two polar asparagine amino acids located near the center of the channel guide the water molecules rapidly through the membrane.

Amino acids are the monomer building blocks of proteins. There are 20 amino acids — each with a di�erent shape and chemical property. As they join together in a distinct sequence — speci�ed by your DNA — they spontaneously fold into a compact shape following basic principles of chemistry and physics.

Life happens in water. The human body is about 70% water. This unique polar solvent provides

the medium in which the macromolecules of your cells �oat. Biomolecules interact with

each other in your cells following basic principles of chemistry and physics.

Each of the structures featured is essential to sustain life.Large biological polymers — DNA, proteins, starch, glycogen and cellulose, and membranes — are composed of smaller “building block” monomers — nucleotides, amino acids, glucose and phospholipids.Aquaporin and other proteins embed in the cell membrane to allow water and other molecules or ions to pass in and out of the cell. Hold the aquaporin and cell membrane models next to each other, as you discuss water transport through the cell membrane. All monomers and polymers featured on the placemat and in the models are shown at the same scale. They are magni�ed 20 million times.The size of an atom is the same in all molecules in which it is present. For example, oxygen, shown in red, is the same size whether it is in a nucleotide, amino acid, sugar, phospholipid or water.

Introduction Exploration

Copyright 3D Molecular Designs - All Rights Reserved - 2009, 2015 Version 4.5

Four classes of biomolecules – proteins, nucleic acids, carbohydrates and lipids – are found in living cells. Proteins, nucleic acids and carbohydrates are macromolecules comprised of a small number of monomeric subunits: amino acids, nucleotides and monosaccharides, respectively. Since they interact in an aqueous environment, we have included water as one of the Molecules of Life. Lipids are a diverse group of molecules that interact with each other through “hydrostatic interactions” rather than covalent bonds, and generally are not large enough to be considered macromolecules.

Remember that these structures are dynamic and �exible, not rigid like the plaster models included in the Molecules of Life Collection©. When teaching the concepts related to the Molecules of Life featured above, you may want to use 3D Molecular Designs’ Water Kit©, DNA Discovery Kit©, Flow of Genetic Information Kit©, Amino Acid Starter Kit©, and Phospholipid & Membrane Transport Kit©.

The Molecules of Life Collection© features plaster models of the 4major types of biomolecules — nucleic acids, proteins, lipids and carbohydrates. Since the biomolecules exist and interact in an aqueous environment, water is also included. Two single building block models go with each biomolecule. A major teaching point is that large complex biomolecules are made of small, simple building block units. All models are built to the same scale — 20 million times their real size.

The models sit on a 24” x 22” placemat that includes a description of each structure. Individual 8.5" x 11" student workstation mats are available online to download and print.

The entire set includes 17 models: DNA, adenosine monophosphate, aquaporin, asparagine, cell membrane, phospholipid, starch, glycogen, cellulose, glucose, ice structure and water molecule. Mini models are made of plaster by 3-D printing and should be handled with care. Models will break if dropped, held tightly or handled roughly.

In the Mitochondria Poster© (top left) your students will see the large protein complexes of the electron transport chain which create the electrochemical gradient that powers ATP synthase to build ATP. ATP is then transported out of the mitochondrion by the adenine nucleotide translocator and diff uses through the channels in the VDAC protein in the outer membrane.

The E. coli Poster© (right) illustrates the inside of an E. coli cell — magnifi ed 1 million times. The molecular complexity of this bacterial cell is emphasized in this image which features a large fl agellum and the motor proteins that power its rotation and a variety of transmembrane proteins that function in transporting molecules into and out of the cell. Also shown are the ribosomes and associated proteins that support bacterial protein synthesis and the DNA, along with the DNA and RNA polymerases that function in replication and transcription.

The Neuromuscular Synapse Poster© (bottom left) illustrates the molecular interactions found at a neuromuscular synapse — where vesicles fi lled with the neurotransmitter, acetylcholine, are fusing with the membrane of the pre-synaptic neuron. Following vesicle fusion, the acetylcholine diff uses across the synaptic space to bind to acetylcholine receptors found in the membrane of the muscle cell. Acetylcholinesterase is entangled in the synaptic space, where it breaks down the neurotrnsmitter, ending neuronal signaling.

David Goodsell, PhD, scientist, author and artist of all things small, creates cellular landscapes that accurately illustrate the size, shape and distribution of proteins in their natural environment of the cell. These unique images connect the molecular world, inferred by X-ray crystallography and NMR spectroscopy, with the cellular world, observed by light and electron microscopy.

These laminated prints of Goodsell’s stunning water color paintings illustrate biology in a dimension not seen in other instructional tools. Adjacent text identifi es the structures and explains their functions. Whether teaching the fl ow of genetic information, the many jobs of proteins, energy metabolism or the immunology of a fl u shot, these landscapes may be the missing piece in your current collection of instructional tools.

Tour of a Human Cell© Detail

The Tour of a Human Cell Panorama© will take your students from the nucleus to the outer cell membrane. In the nucleus, DNA is wrapped around histones forming nucleosomes. RNA polymerase unwraps the DNA and makes mRNA which is delivered through nuclear pore complexes to ribosomes where antibody proteins are made and delivered into the endoplasmic reticulum. Vesicles carry the protein through the Golgi and kinesin motor proteins pull the antibodies to the cell membrane — a wonderful example of the immunology of your fl u shot.

Nucleosome Mini ModelThe nucleosome is the most basic, repeating structural unit of chromosomes. Its central protein core has 8 histones (2 copies each of H2A, H2B, H3 and H4) and 145 base pairs of double-stranded DNA. The N-terminal end of each histone has many positively-charged amino acids that interact with the negatively-charged phosphate backbone of DNA. This model reveals that histones interact only with the minor groove of DNA. The major groove is then available for sequence-specifi c DNA binding proteins, such as Zif 268. 4” Plaster Model $199 (NCSMM)

Large and Small Ribosome Mini ModelsVenkatraman Ramakrishnan, Thomas A. Steitz and Ada E. Yonath won the Nobel Prize in Chemistry in 2009 for studies of the structure and function of the ribosome. (nobelprize.org)

Protein synthesis becomes understandable as your students see the 3 tRNAs of the small (30S) subunit and how they fi t into the cavity of the large subunit (50S) to synthesize proteins. In the large subunit, they will see the single adenosine base (yellow) that catalyzes peptide bond formation during protein synthesis. The large subunit of a bacterial ribosome is a protein-RNA complex composed of 34 proteins and 2 rRNAs (23S and 5S). The rRNA folds into this specifi c 3-D structure, with the proteins serving as the mortar between RNAs. The newly synthesized protein exits the ribosome through a visible channel that extends from the catalytic adenosine to the surface of the ribosome.

The small subunit (30S) of the bacterial ribosome is a protein-rRNA complex composed of 21 proteins and a single RNA (16S). It folds into a specifi c 3-D structure and is stabilized by associated proteins. In this spacefi lled model, two tRNAs (green) dock with their 3’ends close together — ready for peptide bond formation.Pair $358 (R5030SMM) • 4” 50S Ribosome $214 (R50SMM) • 4” 30S Ribosome $184 (R30SMM)

Also see Flow of Genetic Information Kit© (page 13) and Tour of a Human Cell© (page 15).

Transfer RNA Mini ModelsTransfer RNA (tRNA) is a short RNA molecule (76 nucleotides) that delivers amino acids to the ribosome, where they join to a growing chain during protein synthesis. Transfer RNAs fold into 3-D structures, stabilized by hydrogen bonding between complementary bases. In this model, the phosphate backbone of the tRNA is white, the 4 bases are red, the anticodon is blue and the 3’-end (where the amino acid is bound) is yellow. 3.5” Plaster Model $76 (TRNAMM)

3” Nylon Model $175 (NTRNAM)

Nylon tRNARNA folds into complex 3D shapes — just like proteins. This nylon model of tRNA shows the details of this complex 3-D structure — complete with the A-T and G-C base-pairs that stabilize the structure. The model allows students to explore the anti-codon of the tRNA, and the 3' end of tRNA where the charged amino acid is added.

Hemagglutinin Mini ModelThe hemagglutinin protein (HA) of the infl uenza virus plays a critical role in the infection process. These models show the dramatically diff erent shapes of the hemagglutinin HA2 protein at pH 7 and at pH 5. These models will allow you to tell an amazing molecular story — of how the virus takes advantage of the dramatic decrease in pH following the uptake of the virus by receptor-mediated endocytosis. Models magnet-dock onto the base and can be removed for closer examination. Color coding enables students to clearly see the conformational changes that the protein undergoes. This model can be used in conjunction with the Tour of the Human Cell© (page 15) that illustrates a ß-cell that has been stimulated to produce antibodies in response to the fl u vaccine. 6.5” Tall Plaster Mini Model $86 (HAMM)

Antibodies are composed of 12 immunoglobulin folds; 4 in each heavy chain (yellow in the model) and 2 in each light chain (red in the model). The antigen binding site of an antibody is composed of the ends of 2 immunoglobulin folds (1 yellow heavy chain and 1 red light chain) that are positioned at the tips of the Y-shaped antibody. With this model, you can introduce students to concepts of protein structure and function while teaching the immune system.

Infl uenza Virus CapsulesInfl uenza is an RNA virus with a roughly spherical lipid envelope, which is colored yellow on our schematic model. The outside of the virus capsule is covered with 3 specifi c proteins: hemagglutinin (HA, purple), neuraminidase (NA, pink) and the M2 channel (blue). These 3 proteins are involved in virus docking, endocytosis and fusion of the viral membrane to the host cell, the release of newly

budded virus from infected cells, and acidifi cation of the virus core and release of the segmented viral RNA. The specifi c sub-types and combinations of the hemagglutinin (H) and neuraminidase (N) on the surface of the virus capsule categorize the strain of the virus. The viral RNA is represented by 8 segments of RNA — some colored red and some colored yellow — to represent a re-assorted virus emerging from a host cell simultaneously infected with a swine fl u virus and an avian fl u virus (H1N1 swine fl u).

A Project-Based Learning ActivityEngage your students and cover a wide-range of science topics with the true story of California twins Noah and Alexis Beery, who have gene variants that cause them to have life-threatening low levels of three neurotransmitters. Whole genome sequencing in 2010 identifi ed a mutation in the gene that encodes the sepiapterin reductase enzyme, leading to a molecular diagnosis and successful treatment.

This gene map presents the nucleotide sequence of the messenger RNA encoding sepiapterin reductase – the enzyme that was shown to be defective in Noah and Alexis Beery. The map documents the molecular consequence of two diff erent mutations in this gene that were responsible for the neurotransmitter defi ciencies experienced by the Beery twins. Teacher notes and student handouts are available online.

These models show how two amino acids (tyrosine and tryptophan) are converted into two neurotransmitters (dopamine and serotonin) by two consecutive enzyme-catalyzed reactions. Magnet-docked hydroxyl groups, carboxylate groups and hydrogens allow each model to be quickly converted from amino acid to neurotransmitter in two easy steps. Placemats and supporting materials are available online.

Show your students a physical representation of the twins’ genetic mutations and neurotransmitter defi ciencies with the Sepiapterin Reductase Mini Model. Three small, magnet-docked sections of the model are removable, revealing the two mutations that the twins inherited from their parents and the cofactor needed for the production of the neurotransmitters. A placemat and other supporting materials are available online.

Models are made of plaster by 3-D printing and should be handled with care. Models will break if dropped, held tightly or handled roughly.

The Mystery Tube© introduces your students to the practice of science. Research scientists frequently face the challenge of examining an object or organism without taking it apart. As your students fi rst pull the cord on one end and the other end pulls into the tube, they may think the solution is easy. But wait, as they continue their investigation, they will be challenged to describe a model for the inner workings of the Mystery Tube© and provide supporting evidence to defend their hypothesis. Teacher notes and student handouts are available online.

The Data Dilemma©

While using The Data Dilemma© your students will experience the dilemma scientists face when new data indicates the mental model of the object they are researching needs to be modifi ed. As each new data set is introduced and your students form a series of new models — using foam tangram pieces — your students will learn that the practice of science is an ongoing process, not a set of facts published in a textbook or online. How many possible models can your students fi nd? Teacher notes are available online.
