Chains	Enzyme Name	Description	Catalytic Residues
A	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.
