General description

Native glucoamylase from Rhizopus species. Glucoamylase is a multi-domain enzyme that belongs to the glycosyl hydrolase 15 family. It catalyzes the hydrolysis of 1,4-linked α-D-glucose residues in glucosylpolysaccharides, liberating glucose units. Useful for the enzymatic determination of starch.
