Concurrent occurrence of α-amylase inhibitor and stimulator in red kidney bean seed: physiological implications

open access: yesBiologia Plantarum, 2010
It is hypothesized that since protein α-amylase inhibitor (α-AI) and stimulator might be present together in red kidney bean (Phaseolus vulgaris L.) seeds, their in vitro interactions might influence their detection and quantification.

Flavonoids as dual-target inhibitors against α-glucosidase and α-amylase: a systematic review of in vitro studies

open access: yesNatural Products and Bioprospecting, 2023
Abstract Diabetes mellitus remains a major global health issue, and great attention is directed at natural therapeutics. This systematic review aimed to assess the potential of flavonoids as antidiabetic agents by investigating their inhibitory effects on α-glucosidase and α-amylase, two key enzymes involved in ...

α-/β-Glucosidase and α-Amylase Inhibitory Activities of Roselle (Hibiscus sabdariffa L.) Ethanol Extract

open access: yesMCBS (Molecular and Cellular Biomedical Sciences), 2017
Background: Diabetes mellitus is a metabolic disease, characterized by hyperglycemia due to disturbance in both insulin secretion and function. One of theurapeutic approaches is to reduce blood glucose levels by inhbiting α-/β-glucosidase and α-amylase ...

Molecular modeling, docking and dynamics studies of fenugreek (Trigonella foenum-graecum) α-amylase

open access: yes, 2022
α-Amylase catalyses the hydrolysis of glucosidic bonds in polysaccharides such as starch, glycogen and their degradation products. In the present study, the three-dimensional structure of fenugreek (Trigonella foenum-graecum) α-amylase was determined ...

Encouragement of Enzyme Reaction Utilizing Heat Generation from Ferromagnetic Particles Subjected to an AC Magnetic Field. [PDF]

open access: yesPLoS ONE, 2015
We propose a method of activating an enzyme utilizing heat generation from ferromagnetic particles under an ac magnetic field. We immobilize α-amylase on the surface of ferromagnetic particles and analyze its activity.

Expression ofAspergillus oryzaeα-amylase gene inSaccharomyces cerevisiae [PDF]

open access: yesFEMS Microbiology Letters, 1993
Abstract A fragment containing the full length cDNA from Aspergillus oryzae α-amylase has been amplified by PCR using specific synthetic oligonucleotides. The amplified cDNA was designed to favour its expression in yeast by modifying its upstream untranslated region.

Expression of theStreptomyces griseusα-amylase gene inEscherichia coli [PDF]

open access: yesFEMS Microbiology Letters, 1994
The amy gene of Streptomyces griseus was not expressed in Escherichia coli cells due to the lack of recognition of the amy promoter by the E. coli RNA polymerase, as confirmed by using promoter-probe vectors. The expression of the amy gene in E. coli was detected only when the promoter-less gene was placed under the control of the lacZ promoter and was

Isolation and purification of α-amylase inhibitors and their in vitro and in vivo effects on Tribolium castaneum (Herbst) and Callosobruchus maculatus (F.)

open access: yesJournal of Plant Protection Research, 2020
Plant derived α-amylase inhibitors are proteinaceous molecules that regulate the enzyme activity in plants and also protect plants from insect attack. In the current study, 28 accessions of 19 plant species were screened for their α-amylase inhibitory ...

Synthesis and bioactivities evaluation of oleanolic acid oxime ester derivatives as α-glucosidase and α-amylase inhibitors

open access: yesJournal of Enzyme Inhibition and Medicinal Chemistry, 2022
Different oleanolic acid (OA) oxime ester derivatives (3a-3t) were designed and synthesised to develop inhibitors against α-glucosidase and α-amylase. All the synthesised OA derivatives were evaluated against α-glucosidase and α-amylase in vitro.
