ABSTRACT:
The invention relates to a new laccase enzyme, which can be isolated from the strains of theMelanocarpusgenus, theM. albomycesstrain in particular. The pH optimum of the enzyme is within 5–8 and the enzyme works at a temperature of 30–80° C. The isoelectric point of the enzyme is about 4.0 as determined by isoelectric focusing and the molecular weight about 80 kDa, defined by SDS-PAGE. The enzyme is especially well suited to applications, wherein the pH and temperature conditions are high. The invention also relates to a gene that encodes laccase enzyme, and a laccase enzyme produced by recombinant technology.
