Here is a general description:
Catechol oxidase - Wikipedia, the free encyclopedia

Another helpful site:
Catechol Oxidase (Tyrosinase) - Enzymes

This is a good enzyme database: Enzyme Database - BRENDA

Use this site to get the EC (Enzyme Commission) number of the catechol oxidase you are interested in (there are different types of this enzyme) and then use the EC number to do further searches. Google "enzyme information" or "enzyme database" and you will find a few sites where you can enter the EC number of an enzyme to get reaction and activity information.
