Lytic Polysaccharide Monooxygenases: The Microbial Power Tool for Lignocellulose Degradation
Review article, 2016
Lytic polysaccharide monooxygenases (LPMOs) are copper-enzymes that catalyze oxidative cleavage of glycosidic bonds. These enzymes are secreted by many microorganisms to initiate infection and degradation processes. In particular, the concept of fungal degradation of lignocellulose has been revised in the light of this recent finding. LPMOs require a source of electrons for activity, and both enzymatic and plant-derived sources have been identified. Importantly, light-induced electron delivery from light-harvesting pigments can efficiently drive LPMO activity. The possible implications. of LPMOs in plant-symbiont and -pathogen interactions are discussed in the context of the very powerful oxidative capacity of these enzymes.
