Xylanase
From CSBLwiki
Mode of Actions
- Endo-
- "Endo-1,4-beta-xylanase involved in the hydrolysis of xylan, a major structural heterogeneous polysaccharide found in plant biomass representing the second most abundant polysaccharide in the biosphere, after cellulose"[1]
- Endohydrolysis of (1->4)-beta-D-xylosidic linkages in xylans (GH10).
- Exo-
- "Hydrolyzes xylooligosaccharides with a degree of polymerization of greater than or equal to 3, releasing xylose from the reducing end. Only hydrolyzes the beta anomers of xylooligosaccharides, with inversion of anomeric configuration. Hydrolyzes the glucose and xylose-based trisaccharides where xylose is located at the -1 subsite, GXX, XXG and GXG. Does not hydrolyze xylan, chitosan, lichenan, curdlan or carboxymethylcellulose."[2]
- Hydrolysis of (1->4)-beta-D-xylose residues from the reducing end of oligosaccharides (GH8).
