Biosynthesis of Aminovinyl-Cysteine-Containing Peptides and Its Application in the Production of Potential Drug Candidates

Abstract: Bacteria produce a wide array of metabolites to protect themselves from competing microbes. These antimicrobial compounds include peptides with an S-[(Z)-2-aminovinyl]-d-cysteine (AviCys) or S-[(Z)-2-aminovinyl]-(3S)-3-methyl-d-cysteine (AviMeCys) residue, which have been isolated from several different bacterial species. The peptides are structurally diverse: some feature polycyclic backbones, such as the lantibiotic epidermin, and others feature a mostly linear structure, such as cypemycin. Each of the AviCy… Show more

“…3C) (21). The Mib gene cluster (22) encodes a lanthipeptide dehydratase MibB, a lanthipeptide cyclase MibC, a precursor peptide MibA, and a flavin-dependent decarboxylase MibD; the latter protein is likely responsible for introducing an S-[(Z)-2-aminovinyl]-D-cysteine (AviCys) system (23). Furthermore, the Mib cluster also contains a P450 monooxygenase MibO (22).…”

“…A recently discovered novel labionin (Lab) is generated by a subset of class III enzymes [7]. Meanwhile, other diverse enzymatically catalyzed modifications have also been revealed in lantibiotics, leading to special residues such as S-aminovinyl-D-cysteine (AviCys), 2-oxobutyryl (OBu) and lysinoalanine, halogenated tryptophan and hydroxylated aspartic acid [5], [8], [9]. Interestingly, although containing a high percentage of Cys residues, lantibiotics seldom contain disulfide connections as Cys residues are in most cases enzymatically cross-linked with dehydrated Ser or Thr to form thioether or carbacyclic linkages.…”

“…Decarboxylation of a C-terminal cysteine to form an AviCys or AviMeCys (cis-2-aminovinyl-3-S-methyl-D-cysteine, made from threonine) residue occurs in several metabolites (21). AviMeCys is present in the class II lantibiotic mersacidin (22).…”
