Antibiotic peptide structurally related to lantibiotics. Active against M.luteus (MIC=0.2 ug/ml). Has cytotoxic activity against mouse P388 leukemia cells (IC(50)=1.3 ug/ml). Maturation involves the enzymatic conversion of Cys-61 into 2,3-didehydroalanine followed by formation of a thioether bond with Cys-64. The C-terminal meso-lanthionine then undergoes decarboxylation. Dimethylated at the N-terminus. Dimethylation is required for antibiotic activity. The configuration of reformed Cys-61 as the D form was attributed by similarity to related structures. Belongs to the linaridin family.
