Lytic polysaccharide mono-oxygenases (LPMOs) are a recently discovered class of enzymes capable of oxidizing recalcitrant polysaccharides. They currently attract much attention due to their potential use in biomass conversion, notably in the production of biofuels. Past work has identified two discrete sequence-based families of these enzymes termed AA9 (formerly GH61) and AA10 (formerly CBM33). Here we report the discovery of a third family of LPMOs. Using a chitin-degrading exemplar from Aspergillus oryzae, we show that the 3-D structure of the enzyme shares some features of the previous two classes of LPMOs, including a copper active centre featuring the histidine brace active site, but is distinct in terms of its active site details and its EPR spectroscopy. The new AA11 family expands the LPMO clan with the potential to broaden both the range of potential substrates and the types of reactive copper-oxygen species formed at the active site of LPMOs.
