EC 3.2.1.32 Endo-1,3-beta-xylanase. [3 PDB entries]    
2cov

Reaction: Random hydrolysis of (1->3)-beta-D-glycosidic linkages in (1->3)-beta-D- xylans.
Other name(s): Endo-1,3-beta-xylosidase. Xylan endo-1,3-beta-xylosidase. Xylanase.
Comments: This enzyme is found mostly in marine bacteria, which break down the beta(1,3)-xylan found in the cell wall of some green and red algae. The enzyme produces mainly xylobiose, xylotriose and xylotetraose.
