AA9 family lytic polysaccharide monooxygenase A

UniProtKB accession:  A0A223GEC9

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Lytic polysaccharide monooxygenase (LPMO) that depolymerizes crystalline and amorphous polysaccharides via the oxidation of scissile alpha- or beta-(1-4)-glycosidic bonds, yielding C4 oxidation products (PubMed:29057953, PubMed:32818374). Catalysis by LPMOs requires the reduction of the active-site copper from Cu(II) to Cu(I) by a reducing agent and H(2)O(2) or O(2) as a cosubstrate (PubMed:29057953). Cleaves a range of polysaccharides, including cellulose, xyloglucan, mixed-linkage glucan and glucomannan (PubMed:29057953, PubMed:32818374).
