Native Rhizopus sp. Glucoamylase
| Cat# | DIA-190 |
| Abbr | Glucoamylase (Rhizopus sp.) |
| Source | Rhizopus sp. |
| Description | Glucan 1,4-alpha-glucosidase is an enzyme located on the brush border of the small intestine with system name 4-alpha-D-glucan glucohydrolase. This enzyme catalyses the following chemical reaction: Hydrolysis of terminal (1->4)-linked alpha-D-glucose residues successively from non-reducing ends of the chains with release of beta-D-glucose. Most forms of the enzyme can rapidly hydrolyse 1,6-alpha-D-glycosidic bonds when the next bond in the sequence is 1,4. |
| Applications | This enzyme is useful for structural investigation of carbohydrates and for enzymatic determination of α-amylase when coupled with the related enzymes in clinical analysis. |
