Abstract:
Laccases (EC 1.10.3.2) are enzymes from the family of oxidoreductases and it is a polyphenol oxidases (PPO) containing copper and is sometimes known as benzenediol: oxygen oxidoreductase. Compounds such as diamines, phenolic compounds, aromatic amines gets oxidised by laccase, monomer cross-linking, polymer degradation, and ring cleavage of aromatic compounds is also catalyzed by Laccase. So Laccases have great biotechnological significance. They also show low substrate specificity. It was first discovered in extracts of the Japanese lacquer tree Rhus vernicifera. Various organisms like bacteria, fungi, insects, and plants also produce this enzyme. While aromatic substrates are being oxidised by Laccase by withdrawing electrons, two molecules of oxygen are simultaneously reduced to two molecules of water. As an oxidase laccase is used in agricultural, medicinal, and industrial applications, and believed that Laccase plays an important role in morphogenesis, pathogenesis, and lignin degradation. Various harmful wastes such as dyes and chemicals released by many textile and dye industries can be degraded by Laccase. It is also helpful in paper and pulp bleaching, lignin degradation, food processing, and bioremediation.
