Endo-1,3(4)-β-glucanase

Endo-1,3(4)-β-glucanase (, endo-1,3-β- D -glucanase, laminarinase, β-1,3-glucanase,4-glucanase, endo-β-(1→3)- D -glucanase, endo-1,3-1,4-β- D -glucanase, endo-β-(1-3)- D -glucanase, endo-β-1,3-glucanase IV, 1,3-1,4)-β- D -glucan 3(4)-glucanohydrolase) is an enzyme with systematic name 3(or 4)-β- D -glucan 3(4)-glucanohydrolase.    It catalyses the following chemical reaction


 * Endohydrolysis of (1→3)- or (1→4)-linkages in β- D -glucans when the glucose residue whose reducing group is involved in the linkage to be hydrolysed is itself substituted at C-3

Substrates include laminarin, lichenin and cereal D -glucans.
