Monophenol monooxygenase, also known as tyrosinase, is an enzyme that plays a crucial role in the oxidation of phenolic compounds, particularly in the biosynthesis of melanin. It catalyzes the conversion of monophenols to o-diphenols and subsequently to o-quinones, which are important in various biological processes, including pigmentation and defense mechanisms in plants and animals. This enzyme is typically found in a variety of organisms, including fungi, plants, and animals. Tyrosinase is a copper-containing enzyme, which means it requires copper ions for its catalytic activity. It is characterized by its ability to catalyze two distinct reactions: hydroxylation of monophenols and oxidation of o-diphenols. The enzyme's activity can be influenced by factors such as pH, temperature, and the presence of inhibitors or activators. Due to its role in melanin production, tyrosinase is of interest in various fields, including cosmetics, food processing, and medical research, particularly in understanding pigmentation disorders and developing treatments for skin conditions.

Tyrosinase (Polyphenol Oxidase) ex. Mushroom, 600U/mg powder

Tyrosinase (EC 1.14.18.1) is an enzyme that oxydises phenol derivatives (e.g. tyrosine, dopamine). One unit of tyrosinase dissolved in 3mL reaction mixture will cause the absorbance at 280nm to increase by 0.001 in the presence of L-tyrosine at pH 6.5 and 25 °C. L-tyrosine is available here.Lyophilized, from mushroom. Activity ≥1000 unit/mg

Tyrosinase

Tyrosinase (Polyphenol oxidase) is a key rate-limiting enzyme encoded by the TYR gene that controls melanin production and catalyzes tyrosine oxidation.
