"In mammals, L-DOPA can act as a cofactor for the catalyzed reaction; therefore in some resources L-DOPA is shown on both sides of the reaction. GO:0004503 describes the monooxygenation of the monophenol, L-tyrosine. For oxidation of diphenols (including L-DOPA and dopamine), consider instead the term 'catechol oxidase activity ; GO:0004097' and its children." . . "catecholase" . "dopa oxidase" .
