IUBMB Enzyme Nomenclature


Accepted name: glucan 1,4-β-glucosidase

Reaction: Hydrolysis of (1→4)-linkages in (1→4)-β-D-glucans, to remove successive glucose units

Other name(s): exo-1,4-β-glucosidase; exocellulase; exo-β-1,4-glucosidase; exo-β-1,4-glucanase; β-1,4-β-glucanase; β-glucosidase; exo-1,4-β-glucanase; 1,4-β-D-glucan glucohydrolase

Systematic name: 4-β-D-glucan glucohydrolase

Comments: Acts on 1,4-β-D-glucans and related oligosaccharides. Cellobiose is hydrolysed, but very slowly.
