Mannan endo-1,4-beta-mannosidase (EC 3.2.1.78, endo-1,4-beta-mannanase, endo-beta-1,4-mannase, beta-mannanase B, beta-1, 4-mannan 4-mannanohydrolase, endo-beta-mannanase, beta-D-mannanase, 1,4-beta-D-mannan mannanohydrolase) is an enzyme with systematic name 4-beta-D-mannan mannanohydrolase.[1][2] This enzyme catalyses the following chemical reaction

Hydrolysis of (1->4)-beta-D-mannosidic linkages in mannans, galactomannans and glucomannans. This cleavage occurs at random internal sites within the chain, as denoted by the prefix "endo".
