Lytic polysaccharide monooxygenase (LPMO) that depolymerizes crystalline and amorphous polysaccharides via the oxidation of scissile alpha- or beta-(1-4)-glycosidic bonds, yielding C1 and C4 oxidation products. 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. Shows endoglucanase activity on tamarind xyloglucan, as well as on beechwood xylan when combined with phosphoric acid swollen cellulose (PASC). Shows no activity on wheat arabinoxylan, konjac glucomannan, acetylated spruce galactoglucomannan, or cellopentaose
