Function

function

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 (Probable). Catalysis by LPMOs requires the reduction of the active-site copper from Cu(II) to Cu(I) by a reducing agent and H2O2 or O2 as a cosubstrate (Probable).

Catalytic activity

  • [(1->4)-beta-D-glucosyl]n+m + reduced acceptor + O2 = 4-dehydro-beta-D-glucosyl-[(1->4)-beta-D-glucosyl]n-1 + [(1->4)-beta-D-glucosyl]m + acceptor + H2O.
    EC:1.14.99.56 (UniProtKB | ENZYME | Rhea)

Cofactor

Cu2+ (UniProtKB | Rhea| CHEBI:29036 )

Note: Binds 1 copper ion per subunit.

Biotechnology

Lignocellulose is the most abundant polymeric composite on Earth and is a recalcitrant but promising renewable substrate for industrial biotechnology applications. Together with cellobiose dehydrogenases (CDHs) an enzymatic system capable of oxidative cellulose cleavage is formed, which increases the efficiency of cellulases and put LPMOs at focus of biofuel research.
