Glucan 1,4-β-glucosidase

The enzyme glucan 1,4-β-glucosidase, also known as 4-β- D -glucan glucohydrolase, catalyses the hydrolysis of (1→4)-linkages in 1,4-β- D -glucans and related oligosaccharides, removing successive glucose units.

This is one of the cellulases, enzymes involved in the hydrolysis of cellulose and related polysaccharides; more specifically, an exocellulase, that acts at the end of the polysaccharide chain. Other names for this enzyme are exo-1,4-β-glucosidase, exocellulase, exo-β-1,4-glucosidase, exo-β-1,4-glucanase, β-1,4- D -glucanase, exo-1,4-β-glucanase, and 1,4-β- D -glucan glucohydrolase.
