Function

function

Hydrolyzes xylooligosaccharides with a degree of polymerization of greater than or equal to 3, releasing xylose from the reducing end. Has low activity on birchwood xylan, oat spelt xylan and arabinoxylan.

Catalytic activity

  • Hydrolysis of (1->4)-beta-D-xylose residues from the reducing end of oligosaccharides.
