A peptide composed of 40 amino acids (aa) was isolated from the venom of the Gila Monster(Heloderma suspectum, then submitted to various biochemical and chemical treatments.1) After a treatment with a highly specific chymotrypsin, four peptides were generated:- peptide A (6 aa)- peptide B (16 aa)- peptide C (3 aa)- , and peptide D (15 aa)2) Treatment with carboxypeptidases A or B resulted in the release of:- phenylalanine for peptides A and B- tryptophan for peptide C- glycine for peptide D and the 40 amino acids venom peptide3) One cycle of Edman degradation either for peptide A or for the 40 amino acidspeptide gave the exact PTH derivative indicated below: 4) The 40 amino acids peptide treated with Asp-N endopeptidase followed by massspectrometry MS/MS revealed the following composition:- two molecules of glutamic acid,- various peptides indicated below sorted by masses:HG,DLSKQM,EGTFTS,EAVRLFI,EWLKNGGPSSGAPPPSG Information- Chymotrypsin (endopeptidase) hydrolyzes peptide bonds on…
