WebN-methylation of the cysteine amine is rare and is catalyzed by an S -adenosylmethioneine (SAM)-containing enzyme (CT1040) designated N-methyl-bacillithiol synthase A (NmbA). Mutant strains with disruptions in genes involved in BSH biosynthesis or nmbA grew 20% slower than the wild-type strain in media containing sulfide or thiosulfate. WebThiol-containing molecules can interact with metal ions and metal surfaces to form dative bonds. Dative bonds are also known as coordinate covalent bonds. They differ from normal covalent linkages, because they are formed by two electrons coming from a single atom, instead of two atoms each sharing one electron.
