|Section2= |Section3= }} ''O''-Acetylserine is the α-amino acid with the chemical formula HO2CCH(NH2)CH2OC(O)CH3. It is an intermediate in the biosynthesis of the common amino acid cysteine in bacteria and plants. ''O''-Acetylserine is biosynthesized by acetylation of the serine by the enzyme serine transacetylase. The enzyme ''O''-acetylserine (thiol)-lyase, using sulfide sources, converts this ester into cysteine, releasing acetate: :HO2CCH(NH2)CH2OH → HO2CCH(NH2)CH2OC(O)CH3 :HO2CCH(NH2)CH2OC(O)CH3 → HO2CCH(NH2)CH2SH ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「O-Acetylserine」の詳細全文を読む スポンサード リンク
