text: In plants, cysteine is produced from an activated serine, O-acetylserine (OAS) in a two-step reaction sequence catalyzed by two enzymes; (i) serine acetyltransferase (SERAT) which catalyzes the formation of OAS from serine and acetyl coenzyme A and (ii) O-acetylserine(thiol)lyase (OASTL) which catalyzes the formation of cysteine from OAS and sulfide produced by sulfate reduction.
