Unliganded and substrate bound structures of the cellooligosaccharide active lytic polysaccharide monooxygenase LsAA9A at low pH. Carbohydr. Res., 448:187-190, 2017 Cited by PubMed Abstract: Lytic polysaccharide monooxygenases (LPMOs) have been found to be key components in microbial (bacterial and fungal) degradation of biomass. They are copper metalloenzymes that degrade polysaccharides oxidatively and act in synergy with glycoside hydrolases. Recently crystallographic studies carried out at pH 5.5 of the LPMO from Lentinus similis belonging to the fungal LPMO family AA9 have provided the first atomic resolution view of substrate-LPMO interactions. The LsAA9A structure presented here determined at pH 3.5 shows significant disorder of the active site in the absence of substrate ligand. Furthermore some differences are also observed in regards to substrate (cellohexaose) binding, although the major interaction with the N-terminal histidine remains unchanged.
