Maximum enzyme activity of the enzyme at 308 K accounts for pH 4-4.7. It was found that on the catalytic rate constant laccase oxidation of dihydric phenols does not affect their structure. They are rapidly oxidized by the enzyme than trihydric phenols and ascorbic acid. Experimental evidence that the primary products of the oxidation of phenols are semiquinones who take part in further non-enzymatic reactions. Laccase plays the role of initiator radical enzymatic oxidation of polyhydric phenols. In the process of laccase oxidation of pyrogallol by molecular oxygen under mild acidic conditions fixed superweak chemiluminescence. The effect of ethanol and acetonitrile, the catalytic activity of laccase Trametes Versicolor, concentration limits established these solvents, within which the laccase is catalytically active.
