Conclusions 1. Proposed and statistically justified a new paradigm
of the structural organization of proteins, according to which the basic element of a naturally occurring amino acid sequence if information unit.
2. On the basis of the paradigm developed a method of information structure analysis (ANIS) of proteins. The method allows to reveal hierarchically organized structural elements of the informational structure (ELIS) in the amino acid sequences.
3. Demonstrated examples of the ANIS method applications to explain the mechanism of proteins function. In works on protein engineering the method was used for the design of amino acid sequences with modified physico-chemical and functional characteristics, but retains the ability to self-organize.
