EC 3.2.1.32

Accepted name: endo-1,3-β-xylanase

Reaction: Random endohydrolysis of (1→3)-β-D-glycosidic linkages in (1→3)-β-D-xylans

Other name(s): xylanase (ambiguous); endo-1,3-β-xylosidase (misleading); 1,3-β-xylanase; 1,3-xylanase; β-1,3-xylanase; endo-β-1,3-xylanase; 1,3-β-D-xylan xylanohydrolase; xylan endo-1,3-β-xylosidase

Systematic name: 3-β-D-xylan xylanohydrolase

Comments: This enzyme is found mostly in marine bacteria, which break down the β(1,3)-xylan found in the cell wall of some green and red algae. The enzyme produces mainly xylobiose, xylotriose and xylotetraose.
