Introduction: α-amylase is a major form of amylase found in humans and other mammals. It is the special key enzyme involved in carbohydrates breakdown. Inhibition of this enzyme could be used in treatment of diabetes. In this study, the effect of ten Iranian macrolichens on alpha amylase were tested. Methods: Different concentrations of the extracts (25, 50 and 75 mg/ml) were incubated wi...

Bacterial amylase from Bacillus subtilis and fungal amylase from Aspergillus niger were potential source for industrial exploitation in the field of amylase production. Hence, this study on bacterial amylase and fungal amylase was done to compare the kinetic parameter of both the types of amylases. 30-60% ammonium sulfate precipitation has done which showed 90 % of purification of both the part...

in this paper, covalent immobilization of beta amylase enzyme on the surface of modified magnetic nano particles (znfe2o4@sio2-nh2) is reported. for doing so, at first, the magnetic nanoparticles of znfe2o4 were synthesized by chemical co-precipitation method and then tetraethyl orthosilicate (teos) and 3-aminopropyltriethoxy silane (aptes) were used for modification of znfe2o4 nanoparticles wi...

Four halotolerant fungal isolates originating from the saltwater Lake Urmia in Iran were selected during a screening program for salt resistance and α-amylase activity. The isolates were identified based on sequencing the ITS region and a part of the β-tubulin gene, as Penicillium chrysogenum (isolate U1; CBS 132820), Fusarium incarnatum (isolate U2; CBS 132821), and Penicillium polonicum (isol...

To determine the mechanism(s) responsible for glucocorticoid-induced increases in amylase content in pancreatic acinar AR42J cells, we examined the effects of dexamethasone on amylase protein biosynthesis, steady-state mRNA levels, and gene transcription. Dexamethasone treatment led to a dose-dependent increase in amylase synthesis which was one-half maximal at 2 nM and maximal at 100 nM where ...

Background: Alpha-amylase is the most important enzyme in the digestion of starch. Activators of this enzyme could be potentially used as digestive aids and its inhibitors block the absorption of starch compounds and result in the control of blood sugar levels. This study aimed at the investigation of aromatic compounds on bovine serum alpha-amylase. Methods: Effect of carvacrol, cumyl phenol, ...
