[Block principle of organization and polyfunctional nature of regulatory peptides].
Study on the primary structure of more than 100 regulatory peptides was carried out with the view of determining their structural similarity. Practically all regulatory peptides appeared to be related to each other. One regulatory peptide can bear similarity to several regulatory peptides (RPs) which is realized by different fragments. The structural similarity of RPs was in some cases unexpected, e. g., somatocrinin-thymosin, secretin-endorphin, etc. Gastro-intestinal peptides were related to most RPs. It seems likely that these peptides are the most ancient ones among RPs.
