Description

General description

Laccase EC 1.10.3.2, a glycoprotein, is an extracellular multicopper enzyme and is considered as a metal. Laccase is widely distributed in fungi and also found among the higher plants, bacteria and insects.

Biochem/physiol Actions

Laccase oxidizes aromatic and nonaromatic compounds. Various compounds are used for detecting laccase production. These include guaiacol, syringaldazine and polymeric dyes like remazol brilliant blue-R. Laccase is involved in lignin degradation and thereby has industrial as well as food applications. Laccase is commonly used for delignification, dye bleaching, paper processing, waste detoxification, textile dye transformation, plant fiber modification and ethanol production.

Unit Definition

One Unit: LAMU (Laccase Unit). 1 LAMU is defined as the amount of enzyme which oxidizes 1 micromole of syringaldazine per minute, at pH 7.5 and 30 deg C.
