Endohydrolysis of (1->4)-beta-D-xylosidic linkages in xylans
the catalytic residues are two conserved Glu residues, which are located opposite to each other in an open active site cleft. The catalytic mechanism resembles that of lysozyme. The role of one glutamate is to act as an acid/base catalyst whereas the other is a nucleophile and stabilizes the reaction intermediate

xylan + H2O
xylobiose + xylotriose + xylotetraose + ?
the enzyme is most active on xylans with high content of arabinose (rye arabinoxylan and wheat arabinoxylan) than on xylans with low content of arabinose (oat spelts xylan, birchwood xylan and beechwood xylan). It releases xylooligosaccharides but not xylose, indicating that XynA is an endoxylanase
