POST TRANSLATIONAL MATURATION OF LANTIBIOTICS INVOLVES THE ENZYMIC CONVERSION OF THR, AND SER INTO DEHYDRATED AA AND THE FORMATION OF THIOETHER BONDS WITH CYSTEINE. THE CARBOXY-TERMINAL BETA-METHYLLANTHIONINE UNDERGOES DECARBOXYLATION. THIOETHER BONDS WITH CYSTEINE RESULT IN FOUR RINGS. THIS IS FOLLOWED BY MEMBRANE TRANSLOCATION AND CLEAVAGE OF THE MODIFIED PRECURSOR. 由来: (天然) BACILLUS SP. HIL-Y85/54728 (バクテリア) 株: HIL Y-85, 54728 / 参照: UniProt: P43683, Mersacidin
