General annotation (Comments)

Function

Plays an important role in the final stage of carbohydrate digestion.

Catalytic activity

Hydrolysis of sucrose and maltose by an alpha-D-glucosidase-type action.

Hydrolysis of (1->6)-alpha-D-glucosidic linkages in some oligosaccharides produced from starch and glycogen by alpha-amylase, and in isomaltose.

Subunit structure

The resulting sucrase and isomaltase subunits stay associated with one another in a complex by non-covalent linkages.

Subcellular location

Apical cell membrane; Single-pass type II membrane protein. Note: Brush border.

Tissue specificity

Expressed in the poorly differentiated crypt cells of the small intestine as well as in the mature villous cells. Expressed at very low levels in the colon. Ref.5

Post-translational modification

The precursor is proteolytically cleaved when exposed to pancreatic proteases in the intestinal lumen.

Sulfated By similarity.

Involvement in disease

Defects in SI are the cause of congenital sucrase-isomaltase deficiency (CSID) [MIM:222900]; also known as disaccharide intolerance I. CSID is an autosomal recessive intestinal disorder that is clinically characterized by fermentative diarrhea, abdominal pain, and cramps upon ingestion of sugar. The symptoms are the consequence of absent or drastically reduced enzymatic activities of sucrase and isomaltase. The prevalence of CSID is 0.02 % in individuals of European descent and appears to be much higher in Greenland, Alaskan, and Canadian native people. CSID arises due to post-translational perturbations in the intracellular transport, polarized sorting, aberrant processing, and defective function of SI. Ref.6 Ref.7 Ref.8 Ref.9 Ref.10

Miscellaneous

There is a high degree of homology between the isomaltase and sucrase portions (41% of amino acid identity) indicating that this protein is evolved by partial gene duplication.

Sequence similarities

Belongs to the glycosyl hydrolase 31 family.

Contains 2 P-type (trefoil) domains.
