A crystal structure has been determined for tendamistat, the 74-amino acid inhibitor produced by Streptomyces tendae that targets a wide range of mammalian alpha-amylases. [3] The binding of tendamistat to alpha-amylase leads to the steric blockage of the active site of the enzyme.
Alpha-glucosidase inhibitors (AGIs) are oral anti-diabetic drugs used for diabetes mellitus type 2 that work by preventing the digestion of carbohydrates (such as starch and table sugar). They are found in raw plants/herbs such as cinnamon and bacteria (containing the inhibitor acarbose ).
Alpha-amylase inhibition: Inhibition of the alpha-amylase enzyme, decreasing the digestion of starch. [ 3 ] SGLT2 inhibition : Inhibition of sodium-glucose transport protein 2 (SGLT2) decreases glucose reabsorption in the renal tubules of nephrons, thus increasing the amount of glucose excreted in urine.
The starch iodine test, a development of the iodine test, is based on colour change, as α-amylase degrades starch and is commonly used in many applications. A similar but industrially produced test is the Phadebas amylase test, which is used as a qualitative and quantitative test within many industries, such as detergents, various flour, grain ...
Human enzymes do transform acarbose: the pancreatic alpha-amylase is able to perform a rearrangement reaction, moving the glucose unit in the "tail" maltose to the "head" of the molecule. Analog drugs with the "tail" glucose removed or flipped to an α(1-6) linkage resist this transformation. [14]
The maltogenic alpha-amylase is an enzyme which catalyses hydrolysis of (1-4)-alpha-D-glucosidic linkages in polysaccharides so as to remove successive alpha-maltose residues from the non-reducing ends of the chains in the conversion of starch to maltose. Other enzymes in this family include neopullulanase, which hydrolyses pullulan to panose ...
[1] [2] This enzyme catalyses the following chemical reaction. hydrolysis of (1->4)-alpha-D-glucosidic linkages in polysaccharides so as to remove successive alpha-maltose residues from the non-reducing ends of the chains. This enzyme acts on starch and related polysaccharides and oligosaccharides.
Alpha-amylase 1 is an enzyme that in humans is encoded by the AMY1A gene. [3] This gene is found in many organisms. Amylases are secreted proteins that hydrolyze 1,4-alpha-glucoside bonds in oligosaccharides and polysaccharides, and thus catalyze the first step in digestion of dietary starch and g
