Lytic polysaccharide monooxygenases (LPMOs) boost enzymatic depolymerization of recalcitrant polysaccharides, such as chitin and cellulose. We have studied a chitin-active LPMO domain (JdLPMO10A) that is considerably smaller (15.5 kDa) than all structurally characterized LPMOs so far and that is part of a modular protein containing a GH18 chitinase. The 1.55 A resolution structure revealed deletions of interacting loops that protrude from the core beta-sandwich scaffold in larger LPMO10s. Despite these deletions, the enzyme is active on alpha- and beta-chitin, and the chitin-binding surface previously described for larger LPMOs is fully conserved. JdLPMO10A may represent a minimal scaffold needed to catalyse the powerful LPMO reaction. | |||
