[https://www.uniprot.org/uniprot/ | [https://www.uniprot.org/uniprot/LP14B_TRAC3 LP14B_TRAC3] Lytic polysaccharide monooxygenase (LPMO) that oxidatively cleaves xylan with both C1 and C4 regioselectivity and that specifically targets the protective shield made by heteroxylans that cover cellulose microfibrils in wood (PubMed:29377002, PubMed:32793303). 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:29377002). Cleavage occurs only when xylans are bound to cellulose and not when they are in solution (PubMed:29377002). Increases the efficiency of wood saccharification through oxidative cleavage of highly refractory xylan-coated cellulose fibers via synergistic relationship with xylan-active enzymes, xylobiohydrolases and cellobiohydrolases (PubMed:29377002, PubMed:32793303).<ref>PMID:29377002</ref> <ref>PMID:32793303</ref> | ||
