Mannan endo-1,4-β-mannosidase (EC 3.2.1.78, endo-1,4-β-mannanase, endo-β-1,4-mannase, β-mannanase B, β-1, 4-mannan 4-mannanohydrolase, endo-β-mannanase, β-D-mannanase, 1,4-β-D-mannan mannanohydrolase) is an enzyme with systematic name 4-β-D-mannan mannanohydrolase.[1][2] It catalyses the hydrolysis of (1→4)-β-D-mannosidic linkages in mannans, galactomannans and glucomannans. The cleavage occurs at random internal sites within the chain, as denoted by the prefix "endo".
