A unclecapeptide (11 amino acias) was Isolated from a soll microbe cincl subjected to proteolytic digestion and cycnogen bromide cleavage. Results from experiment below: Chymotrypsin treatment produced 3 fragments with the following sequence: met-Pro-G714-Tur LYS-LYS-Leu AICI - ASP - ASP-Phe •Tripsin treatment produced, Augment AKA-ASP-CISP-phe-met-pro-gly-Tur-Lys cyanogen bomide produced 2 fragments. The fragment not bearing the nomoserine lactone was found to have the following sequence: Pro-Gly-Tur-LYS-LYS-Leu
