Method: X-ray diffraction, Resolution 1.49Å Ligands: CL, GCV, GOL, MG, XYP, XYS Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function XYNA1_PAESJ Catalyzes the depolymerization of methylglucuronoxylan (MeGAXn), a beta-1,4 xylan in which 10% to 20% of the xylose residues are substituted with alpha-1,2-4-O-methylglucuronate (MeGA) residues, which is predominant in hemicellulose fractions of hardwood and crop residues. Generates xylobiose (X2) and aldotetrauronate (MeGAX3) as the predominant products of MeGAXn hydrolysis; these products are then directly assimilated by the bacterium for subsequent metabolism. Thus, allows the bacterium to efficiently use polymeric MeGAXn as a growth substrate.
