Grouped By:  Matching UniProtKB accession

UniProtKB description:  Lytic polysaccharide monooxygenase that depolymerizes crystalline and amorphous polysaccharides via the oxidation of scissile alpha- or beta-(1-4)-glycosidic bonds, yielding specifically C1 oxidation product (PubMed:29196788, PubMed:28257189). 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:28257189). Is active on regenerated amorphous cellulose (RAC) in the presence of ascorbic acid or 3-methylcatechol (PubMed:29196788). Acts also on phosphoric acid swollen cellulose (PASC) as a substrate (PubMed:28257189).
