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.
Preparation Note
Following reconstitution, aliquot and freeze (-20°C). Stock solutions are stable for up to 3 months at -20°C. Avoid freeze/thaw cycles of solutions.
