Origin of PeptideProduced as a mixture of closely related congeners by nonribosomal pathway catalyzed by large clusters of peptide and ketide synthetases and peptide/ketide “hybrid” synthetases, respectively
Nature of Peptide/CargoBactericidal antibiotic often used topically. It is a cyclic peptide that contains positively and negatively charged lateral chains at neutral pH and is composed of a mixture of L and D amino acids.
