aromatic-L-amino-acid decarboxylase

ar·o·mat·ic-L-ami·no-ac·id de·car·box·y·lase (ar″o-matґik ə-meґno asґid de″kahr-bokґsə-lās) [EC] an enzyme of the lyase class that catalyzes the decarboxylation of aromatic amino acids, notably converting dopa to dopamine, tryptophan to tryptamine, and hydroxytryptophan to serotonin. The enzyme is bound to a pyridoxal phosphate cofactor and occurs particularly in liver, kidney, brain, and vas deferens; the reaction is important in the biosynthesis of catecholamines and of melanin.
