Laccases (EC 1.10.3.2) are copper-containing oxidase enzymes found in many plants, fungi, and microorganisms. Laccases act on phenols and similar substrates, performing one-electron oxidations, leading to crosslinking. For example, laccases play a role in the formation of lignin by promoting the oxidative coupling of monolignols, a family of naturally occurring phenols. Other laccases, such as those produced by the fungus Pleurotus ostreatus, play a role in the degradation of lignin, and can therefore be classed as lignin-modifying enzymes. Laccases catalyze ring cleavage of aromatic compounds.
