Polyvinyl alcohol-degrading enzyme and process for producing the same

Abstract

The objects of the present invention are to provide a novel PVA-degrading enzyme that the entity of which is revealed at the amino acid sequence level, a process for producing the same, a DNA encoding the enzyme, a recombinant DNA comprising the DNA, and a transformant having the recombinant DNA. The present invention solves the above objects by providing a polyvinyl alcohol-degrading enzyme having the following characteristics (1) to (3), a process for producing the same, a DNA encoding the enzyme, a recombinant DNA comprising the DNA, and a transformant having the recombinant DNA: (1) having an activity of oxidizing polyvinyl alcohol and forming hydrogen peroxide; (2) having an activity of hydrolyzing β-diketone, and (3) exhibiting a molecular weight of 100,000±20,000 in SDS-polyacrylamide gel electrophoresis.
