c-terminal propeptide of bka has a protease sensitive structure without any inhibitory effect on bka
in our previous study, we compared the two α-amylase enzymes from bacillus sp.kr8104, bka∆(n44) and bka∆(n44c193) which is the secreted form of it. the results indicated that the presence of 193 amino acids propeptide in the c-terminal of bka∆(n44) changed its enzymatic parameters like an uncompetitive inhibitor in comparison to bka∆(n44c193). in the present study, we cloned the dna sequence of...
it is now believed that the inhibition of carbohydrate hydrolyzing enzymes (ches) in the digestive tract can significantly prolong the overall carbohydrate digestion time and decrease the postprandial hyperglycemia after a meal. therefore, inhibitors of ches can be useful therapeutic approaches in the management of diabetes mellitus, especially in the type 2, and complications associated with t...
objective(s):one strategy for the treatment of diabetes is inhibition of pancreatic α- amylase. plants contains different chemical constituents with potential for inhibition of α-amylase and hence maybe used as therapeutic. materials and methods: urtica dioica and juglans regia linn were tested for α-amylase inhibition. different concentrations of leaf aqueous extracts were incubated with enzym...

abstract digestive enzyme inhibitors are proteinacious or nonproteinacious compounds which reduce an enzyme activity through attaching to its active site and/or its substrate. nowadays, plant enzyme inhibitors are of great importance because 1) these have considerable effects on insect digestive enzymes and as a result on their development; and 2) the transgenic plants expressing them are safe....
The present review assesses the potential of the Phaseolus vulgaris a-amylase inhibitor isoform 1 (a-AI1) starch blockers as a widely used remedy against obesity and diabetes. Consumption of the a-amylase inhibitor causes marginal intraluminal a-amylase activity facilitated by the inhibitor’s appropriate structural, physico-chemical and functional properties. As a result there is decreased post...
We coupled a kinetic procedure to a selective inhibiting method for determining amylase isoenzymes in biological samples, using 4-nitrophenylmaltopentaoside plus 4-nitrophenylmaltohexaoside as substrate and a wheat-germ selective inhibitor with the Gilford S-III spectrophotometer. On plotting remaining amylase activities/total amylase activities (R/T) vs pancreatic amylase activities/salivary a...
We automated a kinetic procedure for determining amylase isoenzymes in serum and urine samples. We used 4-nitro-phenylmaltoheptaoside as substrate and a selective amylase inhibitor with the Abbott-VP bichromatic system. By use of the maximum differences between pancreatic (P) and salivary (S) amylase activities remaining after inhibition by the selective inhibitor and by use of the linear range...
A simple, rapid screening procedure for determining the relative amounts of pancreatic (P)- and salivary (S)-type amylase in serum is presented, involving incorporation of a selective inhibitor (from wheat-germ) into commercially available BMD Single-Vial Amylase and Beckman Enzymatic Amylase-DS procedures for manual and automated isoamylase measurements. Optimal concentrations of inhibitor inh...
Considered to be an etiologic factor of acute pancreatitis, hypersecretion of pancreatic juice and digestive enzymes is often associated with hyperbilirubinemia. We explored the intracellular mechanisms through which bilirubin affects pancreatic exocrine secretory function by examining the effect of bilirubin on isolated rat pancreatic acini. Bilirubin stimulated amylase release in a concentrat...
