Molecular, Biochemical, and Dietary Regulation Features of α-Amylase in a Carnivorous Crustacean, the Spiny Lobster Panulirus argus. [PDF]

PLoS ONE, 2016
Alpha-amylases are ubiquitously distributed throughout microbials, plants and animals. It is widely accepted that omnivorous crustaceans have higher α-amylase activity and number of isoforms than carnivorous, but contradictory results have been obtained ...

Isolation and characterization of α ‐amylase encoding gene in Bacillus amyloliquefaciens PAS

Indonesian Journal of Biotechnology, 2021
Amylolytic bacteria are a source of amylase, which is an essential enzyme to support microalgae growth in the bioreactor for microalgae culture. In a previous study, the highest bacterial isolate to hydrolyze amylum (namely PAS) was successfully isolated

Immobilization of Trichoderma harzianum α-Amylase on Treated Wool: Optimization and Characterization

Molecules, 2014
α-Amylase from Trichoderma harzianum was covalently immobilized on activated wool by cyanuric chloride. Immobilized α-amylase exhibited 75% of its initial activity after 10 runs.

Synthesis and Molecular Docking Studies of Alkoxy- and Imidazole-Substituted Xanthones as α-Amylase and α-Glucosidase Inhibitors

Molecules, 2023
Current antidiabetic drugs have severe side effects, which may be minimized by new selective molecules that strongly inhibit α-glucosidase and weakly inhibit α-amylase.

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

Biologia 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.
