BiosynthesisofCysteinefromserineinbacteriaandplants
In animals cysteine is synthesized from homocysteine, a produce of the essential amino acid methionine. In the absence of dietary methionine, animals cannot make cysteine. Bacteria and plants however produce cysteine by a different biosynthetic route. The sulfur used to produce cysteine originates from inorganic sulfur taken up from the environment as sulfate. The inorganic sulfur in sulfate is activated by forming a......阅读全文
