Mannan endo-1,4-β-mannosidase

Mannan endo-1,4-β-mannosidase (, 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. 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".
