Formation of an aminovinyl-cysteine residue in thioviridamides occurs through a path independent of known lanthionine synthetase activity
{{output}}
2-Aminovinyl-cysteine (AviCys) is a thioether amino acid shared by a variety of ribosomally synthesized and posttranslationally modified peptides (RiPPs). Based on investigations into the biosynthesis of thioviridamide RiPPs in Streptomyces sp. NRRL S-87, we h... ...
