Term Information

Accession: GO:0004503
Name: tyrosinase activity
Ontology: molecular_function
Synonyms: L-tyrosine monooxygenase activity, monophenol monooxygenase activity, monophenol oxygenase, N-acetyl-6-hydroxytryptophan oxidase activity, catecholase, chlorogenic acid oxidase activity, chlorogenic oxidase activity, cresolase activity, dopa oxidase, monophenol monooxidase activity, monophenol oxidase activity, monophenolase activity, o-diphenol oxidase activity, o-diphenol oxidoreductase, o-diphenol:O2 oxidoreductase activity, prophenol oxidase activity, prophenoloxidase activity, tyrosine-dopa oxidase activity, phenol oxidase activity, phenolase activity, pyrocatechol oxidase
Alternate IDs: None
Definition: Catalysis of the reaction: L-tyrosine + O2 = L-DOPAquinone + H2O. This reaction can use both monophenols (such as tyrosine) and catechols (o-diphenols) as substrates. Source: PMID:4965136, RHEA:18117
Comment: 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.
