== Function ==
[https://www.uniprot.org/uniprot/XYNA1_PAESJ 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.<ref>PMID:16461704</ref>
