Method: X-ray diffraction, Resolution 1.85Å Ligands: BMA, EDO, GCV, GLY, MAN, NAG, PEG, XYP Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function XY30A_MYCTT Xylanase exhibiting endo- and exo-xylanase activity (PubMed:31110561). Shows the highest activity toward beechwood glucuronoxylan, which consists of a beta-1,4-linked xylose backbone decorated with the methylated form of D-glucuronic acid (MeGlcA) attached directly to the main chain at xylose C2 (PubMed:31110561). Acts also against wheat arabinoxylan, a xylan without MeGlcA substituents along the main chain, but the xylanase activity is about two orders of magnitude lower than that achieved in the case of beechwood xylan (PubMed:31110561). Shows no activity against carob galactomannan, konjac glucomannan, or barley beta-glucan (PubMed:31110561). The recombinant xylanase also exhibits an exo-activity by releasing processively disaccharide units from the non-reducing end of linear and decorated xylooligosaccharides (XOS) (PubMed:31110561).
