英文摘要: Lytic polysaccharide monooxygenases (LPMOs) are recently discovered oxidative enzymes that are capable of oxidative cleavage of recalcitrant polysaccharides such as chitin or cellulose. Despite the importance of LPMOs in biomass conversion and the large number of lpmo genes in microorganisms, only a few LPMOs have been well studied, and further characterization of these proteins is thus of interest. In this study, a chitin-active AA10 family LPMO from Bacillus thuringiensis subsp. kurstaki, BtLPMO10A, is described. This enzyme generates even-numbered oxidized oligosaccharides as the dominated products from crystalline chitin, however, interestingly, when colloidal chitin is used as the substrate, a ladder of oxidized oligosaccharides is observed. These results provide new insights into the action mode of LPMOs that may be affected by the substrates. (C) 2015 Elsevier B.V. All rights reserved.
