Preparation and Storage
Stability and Storage
Shipped on dry ice. Upon delivery aliquot and store at -80ºC. Avoid freeze / thaw cycles.
pH: 8.00 Constituents: 0.3% Glutathione, 0.79% Tris HCl
Oligosaccharide alpha 1, 6 glucosidase
sucrase isomaltase alpha glucosidase
Plays an important role in the final stage of carbohydrate digestion.
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.
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.
Belongs to the glycosyl hydrolase 31 family. Contains 2 P-type (trefoil) domains.
The precursor is proteolytically cleaved when exposed to pancreatic proteases in the intestinal lumen. Sulfated.
