This entry represents the copper-containing enzyme laccase ( 1.10.3.2 ), often present in mutiple copies in a single plant species, and additional, uncharacterised, closely related plant proteins termed laccase-like multicopper oxidases. These enzymes show considerable sequence similarity to the L-ascorbate oxidases ( 1.10.3.3 ). Laccases are enzymes of rather broad specificity, acting on both o- and p-quinols, and often acting also on aminophenols and phenylenediamine [ 1 ].
