Mannan 1,4-mannobiosidase (EC3.2.1.100, 1,4-β-D-mannan mannobiohydrolase, exo-β-mannanase, exo-1,4-β-mannobiohydrolase) is an enzyme with systematic name4-β-D-mannan mannobiohydrolase.[1] It catalyses the hydrolysis of (1→4)-β-D-mannosidic linkages in (1→4)-β-D-mannans, to remove successive mannobiose residues from the non-reducing chain ends.
