[A model of intra- and intermolecular interactions of peptide chains].

Results of attempts to determine the code of interaction of amino acids in peptide chains proceeding from their coding nucleotide sequences have been summarized. According to the model suggested the G/C and A/U complementarity of codon roots determines the mutual binding of coded amino acid residues. Structures of analogs of the immunoactive peptide, a fragment of IgG1 (336-370) EPQVY have been constructed on the basis of the model.
