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
PF00264Common central domain of tyrosinase (Tyrosinase)Common central domain of tyrosinaseThis family also contains polyphenol oxidases and some hemocyanins. Binds two copper ions via two sets of three histidines. This family is related to Pfam:PF00372.Domain

catechol oxidase  M-CSA #125

Catechol oxidase is a type 3 copper protein that exclusively catalyses the oxidation of catechols (e.g. o-diphenols) to the corresponding o-quinones. The enzyme can also act on a variety of substituted catechols. Although a member of the same superfamily as tyrosinase, it is a different enzyme.
