== Function ==
[https://www.uniprot.org/uniprot/LP11B_ASPFU LP11B_ASPFU] Lytic polysaccharide monooxygenase (LPMO)-like protein that acts as a strict peroxygenase and does not catalyze a monooxygenase reaction (PubMed:34567832). It is indeed hardly active on chitin, while being very active on soluble oligomers of N-acetylglucosamine (PubMed:34567832). Cleaves the glycosidic bonds byoxidizing the C1 position (PubMed:34567832). Also unable to oxidize cellopentaose (PubMed:34738811). Probably breaks glycosidic bonds in non-polymeric substrates possibly carbohydrates in the cell wall of the fungus or its competitors (PubMed:34567832). In the presence of chitotetraose, the enzyme can withstand considerable amounts of H(2)O(2), which it uses to efficiently and stoichiometrically convert this substrate (PubMed:34567832).<ref>PMID:34567832</ref> <ref>PMID:34738811</ref>
