| Abstract: | Data on the primary structure of approximately 250 proteins and regulatory peptides are presented. It was shown that functionally different proteins contain homologous sequencies. Growth hormone molecule contains homologous sequencies to several proteins. On the whole, polypeptide hormones more frequently, as compared to other proteins, contained sequencies, which are homologous to fragments of proteins with various functions. Evolutionary aspects of multiple relations between proteins are discussed. |
