Sucrose alpha-glucosidase (EC 3.2.1.48, sucrose alpha-glucohydrolase, sucrase, sucrase-isomaltase, sucrose.alpha.-glucohydrolase, intestinal sucrase, sucrase(invertase)) is an enzyme with systematic name sucrose-alpha-D-glucohydrolase.[1][2][3][4][5][6] This enzyme catalyses the following chemical reaction
- Hydrolysis of sucrose and maltose by an alpha-D-glucosidase-type action
This enzyme is isolated from intestinal mucosa as a single polypeptide chain. The human sucrase-isomaltase is a dual-function enzyme with two GH31 domains, one serving as the isomaltase, the other serving as a sucrose alpha-glucosidase.
