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

This domain family is found in bacteria and eukaryotes, and is approximately 50 amino acids in length, and the family is found in association with Pfam:PF00264. Most members are annotated as being polyphenol oxidases, and many are from plants or plastids. There is a conserved DWL sequence motif which gives the family its name.	Domain
