Influence of a Novel Magnetic Recoverable Support on Kinetic, Stability and Activity of Beta-amylase Enzyme
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 sil...
متن کاملA novel alpha-amylase inhibitor from amaranth (Amaranthus hypocondriacus) seeds.
The major alpha-amylase inhibitor (AAI) present in the seeds of Amaranthus hypocondriacus, a variety of the Mexican crop plant amaranth, is a 32-residue-long polypeptide with three disulfide bridges. Purified AAI strongly inhibits the alpha-amylase activity of insect larvae (Tribolium castaneum and Prostephanus truncatus) and does not inhibit proteases and mammalian alpha-amylases. AAI was sequ...

متن کاملRedox regulation of a novel plastid-targeted beta-amylase of Arabidopsis.
Nine genes of Arabidopsis (Arabidopsis thaliana) encode for beta-amylase isozymes. Six members of the family are predicted to be extrachloroplastic isozymes and three contain predicted plastid transit peptides. Among the latter, chloroplast-targeted beta-amylase (At4g17090) and thioredoxin-regulated beta-amylase (TR-BAMY; At3g23920; this work) are experimentally demonstrated to be targeted to p...
متن کاملBioactivity-Guided Separation of an α-Amylase Inhibitor Flavonoid from Salvia virgata
It is now believed that the inhibition of carbohydrate hydrolyzing enzymes (CHEs) in the digestive tract can significantly prolong the overall carbohydrate digestion time and decrease the postprandial hyperglycemia after a meal. Therefore, inhibitors of CHEs can be useful therapeutic approaches in the management of diabetes mellitus, especially in the type 2, and complications associated with t...
