In molecular biology, tyrosinase is an oxidase that is the rate-limiting enzyme for controlling the production of melanin. It is mainly involved in two distinct reactions of melanin synthesis; firstly, the hydroxylation of a monophenol and secondly, the conversion of an o-diphenol to the corresponding o-quinone. o-Quinone undergoes several reactio...

Is a copper-containing enzyme of cats (and other organisms) that is a catalyst in the conversion of tyrosine to the pigment melanin. The enzyme essential in synthesis of melanin and inactivity of this enzyme results in albinism. Tyrosinase is also thermal liable (temperature sensitive). See Thermal liable tyrosinase.

<enzyme> A copper containing protein (a monoxygenase) that catalyses the oxidation of tyrosine and sets in train spontaneous reactions that yield melanin, the black pigment of skin, hair and eyes. The first intermediate is 3, 4 dihydroxyphenylalanine (DOPA). Lack of tyrosinase activity is responsible for albinism. ... (18 Nov 1997) ...
