The special redox chemistry of sulfur and the thiol group in particular proved to be a versatile tool during evolution, not the least in electron transport processes in association with iron.
Cysteine Metabolism and Its Regulation in Bacteria
In animals, biosynthesis begins with the amino acid serine. The sulfur is derived from methionine, which is converted to homocysteine through the intermediate S-adenosylmethionine. Cystathionine beta-synthase then combines homocysteine and serine to form the asymmetrical thioether cystathionine. The enzyme cystathionine gamma-lyase converts the cystathionine into cysteine and alpha-… WebJan 16, 2024 · For biotechnological L-cysteine production, the bacteria C. glutamicum and E. coli harbouring optimised plasmids represent the dominant expression organisms. … phim blondeau
