Enhanced Biomass Degradation by Polysaccharide Monooxygenases

The degradation of cellulose is typically described as a process that relies solely on the action of hydrolytic enzymes. Although it had been suggested that this picture was incomplete, no additional activities could be identified during many decades of intensive research. Very recently, however, the discovery of polysaccharide monooxygenases (PMO) shed new light on the degradation process and paved the way for a much more efficient use of renewable resources. Indeed, PMOs were found to render cellulose chains more accessible for hydrolytic enzymes by disrupting the substrate's crystal packing through an oxidative cleavage reaction. These findings constitute a major breakthrough in biomass research but are still not completely understood. In this chapter, an up-to-date overview will be presented of our current knowledge about the function, structure and mechanism of this new class of enzymes.
