This domain family is found at the C-terminus of a family of tyrosinase enzymes Pfam:PF00264. The tyrosinase family proteins are chloroplastic enzymes that catalyze the oxidation of mono- and o-diphenols to o-diquinones. These reactions are crucial in the formation of melanin and other pigment compounds in plants. The enzymatic activity of these proteins is essential for the browning process in damaged or ripe fruits and vegetables, and plays a role in plant defense mechanisms.	Domain
