Expression ofAspergillus oryzaeα-amylase gene inSaccharomyces cerevisiae [PDF]
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.

Encouragement of Enzyme Reaction Utilizing Heat Generation from Ferromagnetic Particles Subjected to an AC Magnetic Field. [PDF]
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 of theStreptomyces griseusα-amylase gene inEscherichia coli [PDF]
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

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 ...

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.

Suppression of growth defects of α-amylase secretingEscherichia coliby signal sequence fusion [PDF]
Two fusions of the Bacillus stearothermophilus α-amylase gene (amyS) with lacpoZ′ were constructed. The first, being a transcriptional fusion, placed amyS directly under lac promoter control eliminating interference by the endogenous promoter. IPTG induction of amyS transcription in this construction resulted in liberation of periplasmic proteins and ...

Research progress on enhancement of bacterial α-amylase activity
α-amylase is an endonuclease that acts on the α-1,4-glucoside bond of starch molecules to reduce starch viscosity. As a commonly used additive in animal feed, α-amylase can make up for the deficiency of animal amylase, accelerate the starch ...

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