3. Function
• The enzyme found under class xylose which
degrade the linear polysachharide into
xylose.
• Thus, this enzyme also function in degrade
one of plant cell wall major component
which is hemicellulose.

4. Reaction
• Endohydrolysis of (1->4)-beta-D-xylosidic
linkages in xylans.

5. Active Site

6. Application in
Industry
