Entropy Analysis of Protein Sequences Reveals a Hierarchical Organization.

ABSTRACT:

Background

Analyzing the local sequence content in proteins, earlier we found that amino acid residue frequencies differ on various distances between amino acid positions in the sequence, assuming the existence of structural units.

Methods

We used informational entropy of protein sequences to find that the structural unit of proteins is a block of adjacent amino acid residues-"information unit". The ANIS (ANalysis of Informational Structure) method uses these information units for revealing hierarchically organized Elements of the Information Structure (ELIS) in amino acid sequences.

Results

The developed mathematical apparatus gives stable results on the structural unit description even with a significant variation in the parameters. The optimal length of the informa
