Sucrose alpha glucosidase

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. 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.
