ENZYMATIC ACTIVITY OF LYTIC POLYSACCHARIDE MONOOXYGENASE

摘要

The present invention is in the area of enzymes for (hemi )cellulose degradation and/or modification more in particular the degradation and/or modification of xylan. The invention is based on a newly discovered enzymatic activity of a class of lytic polysaccharide monooxygenases (LPMOs) i.e.oxidative cleavage of xylan in addition to oxidative cleavage of cellulose. The present invention therefore relates to a method for degrading and/or modifying xylan in a xylan comprising substrate a method for preparing a product from a xylan comprising substrate a kit of parts a liquid paste or solid formulation and a xylan comprising composition comprising said LPMO. The invention further relates to a use of said LPMO said kit of parts said formulation and/or said composition in a method of the invention.
