THE PYRROLOQUINOLINE-QUINONE (PQQ)-DEPENDENT QUINOHEMOPROTEIN PYRANOSE DEHYDROGENASE FROM COPRINOPSIS CINEREA (CCPDH), BELONGING TO THE AA12 FAMILY, DRIVES LYTIC POLYSACCHARIDE MONOOXYGENASE (LPMO) ACTION

摘要

Fungi secrete a set of glycoside hydrolases and oxidoreductases, including lytic polysaccharide monooxygenases (LPMOs), for the degradation of plant polysaccharides. LPMOs accelerate the decomposition of cellulose by cellulases by catalyzing the oxidative cleavage of glycosidic bonds after activation by an external electron donor (1-3).
