tyrosinase
Tyrosinase is an enzyme that plays a crucial role in the production of melanin, the pigment responsible for the color of skin, hair, and eyes in many organisms. It catalyzes the oxidation of tyrosine, an amino acid, into dopa and then into dopaquinone, which are key steps in melanin synthesis.
This enzyme is found in various organisms, including humans, and is important for protecting the skin from UV radiation. Abnormal tyrosinase activity can lead to conditions such as albinism or vitiligo, affecting pigmentation and overall skin health.
