sucrase-isomaltase complex

sucrase-isomaltase complex
the enzyme complex comprising sucrase and α-dextrinase (isomaltase) activities, occurring in the brush border of the intestinal mucosa and hydrolyzing maltose as well as maltotriose and some other glycosidic bonds; the enzymes are synthesized as a single polypeptide and cleaved to form a heterodimer, each possessing a separate catalytic site. See also sucrase-isomaltase deficiency, under deficiency.
