The three-dimensional structure of the amaranth alpha-amylase inhibitor (AAI) adopts a knottin fold of abcabc topology. Upon binding to alpha-amylase, it adopts a more compact conformation characterized by an increased number of intramolecular hydrogen bonds, a decreased volume and in addition a trans to cis isomerization of Pro20. A systematic analysis of the 3-D structural databanks revealed ...
Pure amylase was isolated from pancreata and parotid glands of the baboon, an animal which has a serum amylase level and renal clearance of amylase (C(Am)) similar to man. After bolus injection, both pancreatic and salivary amylase rapidly disappeared from the serum in a monoexponential fashion with a mean serum half-time of approximately 83 min. Only about 24% of the amylase cleared from the s...
Pancreatic proteases in the duodenum inhibit the release of cholecystokinin (CCK) and thus exert feedback control of pancreatic exocrine secretion. Exclusion of proteases from the duodenum either by the diversion of bile-pancreatic juice or by the addition of protease inhibitors stimulates exocrine pancreatic secretion. The mechanism by which pancreatic proteases in the duodenum regulate CCK se...
Introduction: Sambiloto (Andrographis paniculata) is an antidiabetic medicinal plant that acts by inhibiting the ?-amylase enzyme. Andrographolide, active compound of sambiloto leaf, insoluble in water but dissolves ethanol. Aim: This study compared vitro activity aqueous extract and ethanolic leaf with Methods: The inhibitory test enzyme was carried out using ultraviolet-visible spectrophotome...
Inhibitor activity against digestive enzymes, such as α-amylase from human saliva and porcine pancreas and trypsin from bovine pancreas, of three cereal grains species were studied as potential components of nutraceuticals strengthening diabetes and obesity treatment. Significant differences were demonstrated: the highest antitryptic activity was found in the grain of the rye varieties studied,...
There are major issues regarding the proposed pathway for starch degradation in germinating cereal grain. Given the commercial importance but genetic intractability of the problem, we have embarked on a program of chemical genetics studies to identify and dissect the pathway and regulation of starch degradation in germinating barley grains. As a precursor to in vivo studies, here we report syst...
Microbial fermentation could produce many active substances in green and pollution-free ways. In recent years, studies on the hypoglycemic ability of microorganisms had become a trending topic prevention treatment diabetes. Garlic is food containing variety biologically physiological functions, but it not accepted by general public because its strong pungent smell. our study, with potential eff...
