In enzymology, a dihydroxyphenylalanine ammonia-lyase () is an enzyme that catalyzes the chemical reaction :3,4-dihydroxy-L-phenylalanine trans-caffeate + NH3 Hence, this enzyme has one substrate, 3,4-dihydroxy-L-phenylalanine (L-DOPA), and two products, trans-caffeate and NH3. This enzyme belongs to the family of lyases, specifically ammonia lyases, which cleave carbon-nitrogen bonds. The systematic name of this enzyme class is 3,4-dihydroxy-L-phenylalanine ammonia-lyase (trans-caffeate-forming). Other names in common use include beta-(3,4-dihydroxyphenyl)-L-alanine (DOPA) ammonia-lyase, and 3,4-dihydroxy-L-phenylalanine ammonia-lyase. This enzyme participates in tyrosine metabolism. == 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「Dihydroxyphenylalanine ammonia-lyase」の詳細全文を読む スポンサード リンク
