α-Amylase is an enzyme (EC 3.2.1.1; systematic name 4-α-D-glucan glucanohydrolase) that hydrolyses α bonds of large, α-linked polysaccharides, such as starch and glycogen, yielding shorter chains thereof, dextrins, and maltose, through the following biochemical process: [2]
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.
Glucan 1,4-α-glucosidase (EC 3.2.1.3, glucoamylase, amyloglucosidase, γ-amylase, lysosomal α-glucosidase, acid maltase, exo-1,4-α-glucosidase, glucose amylase, γ-1,4-glucan glucohydrolase, acid maltase, 1,4-α-D-glucan glucohydrolase) is an enzyme located on the brush border of the small intestine with systematic name 4-α-D-glucan glucohydrolase.
Acarbose also blocks pancreatic alpha-amylase in addition to inhibiting membrane-bound alpha-glucosidases. Pancreatic alpha-amylase hydrolyzes complex starches to oligosaccharides in the lumen of the small intestine. Inhibition of these enzyme systems reduces the rate of digestion of carbohydrates.
The reason is most likely because amylopectin is highly branched and these branches are more available to digestive enzymes. In contrast, amylose tends to form helices and contain hydrogen bonding. [23] The breakdown of starch is dependent on three enzymes, among others: [16] [19] [21] alpha, beta amylases; phosphorylases; starch debranching ...
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.
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
In neopullulanase the barrel is located within domain A with its active site straddling domain A of one monomer with domain N of the other monomer. This results in narrower active site than the other alpha-amylase enzymes, which do not dimerize, and likely contributes to its ability of hydrolyzing both alpha-1,4- and alpha-1,6-glucosidic linkages.
