Laccases (EC 1.10.3.2) are copper-containing oxidase enzymes that are found in many plants fungi and microorganisms. The copper is bound in several sites; Type 1 Type 2 and/or Type 3. The ensemble of types 2 and 3 copper is called a trinuclear cluster (see figure). Type 1 copper is available to action of solvents such as water. It can be displaced by mercury substituted by cobalt or removed via a copper complexone. Removal of type 1 copper causes a decrease in laccase activity.
