A New Enzyme Family Catalyzing Methyllanthionine Sulfoxide Formation in Anti-phage Lanthipeptides
Lanthipeptides are one of the largest classes of ribosomally synthesized and post-translationally modified peptides (RiPPs). The coi biosynthetic gene cluster (BGC) from Streptomyces coelicolor A3(2) encodes a canonical class I lanthipeptide dehydratase (CoiB) and cyclase (CoiC), a bifunctional enzyme (CoiSA) with an O-methyltransferase (MT) and glutamyl lyase (GL) domain, and a protein of…
