Endo-1,3-beta-xylanase (EC, xylanase, endo-1,3-beta-xylosidase, 1,3-beta-xylanase, 1,3-xylanase, beta-1,3-xylanase, endo-beta-1,3-xylanase, 1,3-beta-D-xylan xylanohydrolase, xylan endo-1,3-beta-xylosidase) is an enzyme with systematic name 3-beta-D-xylan xylanohydrolase.[1][2][3][4][5] This enzyme catalyses the following chemical reaction

Random endohydrolysis of (1->3)-beta-D-glycosidic linkages in (1->3)-beta-D-xylans

This enzyme is found mostly in marine bacteria.
