Xylanases

特許 権利維持 Xylanase (EC 3.2.1.8, endo-(1->4)-beta-xylan 4-xylanohydrolase, endo-1,4-xylanase, endo-1,4-beta-xylanase, beta-1,4-xylanase, endo-1,4-beta-D-xylanase, 1,4-beta-xylan xylanohydrolase, beta-xylanase, beta-1,4-xylan xylanohydrolase, beta-D-xylanase) is the name given to a class of enzymes which degrade the linear polysaccharide beta-1,4-xylan into xylose,[1] thus breaking down hemicellulose, one of the major components of plant cell walls. As such, it plays a major role in micro-organisms thriving on plant sources for the degradation of plant matter into usable nutrients. Xylanases are produced by fungi, bacteria, yeast, marine algae, protozoans, snails, crustaceans, insect, seeds, etc.,[2] (mammals do not produce xylanases). However, the principal commercial source of xylanases is filamentous fungi.
