EC 3.2.1.39     
Accepted name: glucan endo-1,3-β-D-glucosidase
Reaction: Hydrolysis of (1→3)-β-D-glucosidic linkages in (1→3)-β-D-glucans
Other name(s): endo-1,3-β-glucanase; laminarinase; laminaranase; oligo-1,3-glucosidase; endo-1,3-β-glucanase; callase; β-1,3-glucanase; kitalase; 1,3-β-D-glucan 3-glucanohydrolase; endo-(1,3)-β-D-glucanase; (1→3)-β-glucan 3-glucanohydrolase; endo-1,3-β-D-glucanase; endo-1,3-β-glucosidase; 1,3-β-D-glucan glucanohydrolase
Systematic name: 3-β-D-glucan glucanohydrolase
Comments: Different from EC 3.2.1.6 endo-1,3(4)-β-glucanase. Very limited action on mixed-link (1→3,1→4)-β-D-glucans. Hydrolyses laminarin, paramylon and pachyman.
