The current objective of the study is to evaluate the α-amylase inhibitory activity of butein and tricetin using in silico docking studies. In this perspective, butein and tricetin ligands were prepared for the docking evaluation. Acarbose, a known α-amylase inhibitor was used as the standard. In silico docking studies were carried out using recent version of AutoDock 4.2, which has the basic p...

BACKGROUND Alkaline α-amylases have potential applications for hydrolyzing starch under high pH conditions in the starch and textile industries and as ingredients in detergents for automatic dishwashers and laundries. While the alkaline α-amylase gains increased industrial interest, the yield of alkaline α-amylases from wild-type microbes is low, and the combination of genetic engineering and p...

Genetically modified (GM) legumes expressing the α-amylase inhibitor 1 (αAI-1) from Phaseolus vulgaris L. or cysteine protease inhibitors are resistant to several bruchid pests (Coleoptera: Chrysomelidae). In addition, the combination of plant resistance factors together with hymenopteran parasitoids can substantially increase the bruchid control provided by the resistance alone. If the strateg...

Midgut α-amylase is an important digestive enzyme involved in larval energy metabolism and carbohydrate assimilation. In this article, the properties of midgut α-amylase from the Oriental armyworm, Mythimna separata (Lepidoptera: Noctuidae), larvae were characterized, and its in vitro responses to chemical inhibitors were also determined. The kinetic parameters Km and Vmax of midgut α-amylase w...

Acarbose is a well-known inhibitor of α-glucosidases, α-amylases, cyclomaltodextrin glucanyltransferase (CGTase), and dextransucrase. Bacillus stearothermophilus maltogenic amylase (BSMA) was found to hydrolyze acarbose to give acarviosine-glucose plus glucose and to carry out a transglycosylation reaction to give isoacarbose. Acarviosine-glucose was a potent inhibitor of baker’s yeast α-glucos...

the experiment was conducted to determine α-amylase activity and the effect of seven plant species extracts including punica granatum l. (punicaceae), rheum officinale b. (polygonaceae), rhus coriaria l. (anacardiaceae), artemisia sieberi b. ( compositae), peganum harmala l. (nitrariaceae) , datura stramonium l. (solanaceae) and thymus vulgaris l. (lamiaceae) on α-amylase activity of four store...
