Chains	Enzyme Name	Description	Catalytic Residues
A	glucan 1,4-alpha-glucosidase M-CSA #393	Glucoamylase (alpha-1,4-D-glucan glucohydrolase) catalyses the removal of beta-D-glucose from the non-reducing ends of starch and other related poly- and oligosaccharides. The enzyme is used widely in industry for the conversion of starch to glucose syrups. The glucose in turn is used in the production of fructose sweeteners, ethanol and light beer.
