The Role of Highly Conserved Tryptophan in the Sixth Conserved Region at Substrate Specificity of α- amylase
Early in this study, an α-Amylase from Bacillus megaterium WHO (BMW) was isolated from hot springs of Ramsar (North of Iran), and its gene was cloned in E.coli. Based on its conserved sequence regions and substrate specificity, it was classified as intermediary group enzymes with the specificity of oligo-1,6-glucosidase and neopullulanase subfamilies. In the sixth conserved re...
متن کاملNovel endo-α-N-acetylgalactosaminidases with broader substrate specificity
In an effort to identify novel endo-alpha-N-acetylgalactosaminidases (endo-alpha-GalNAcases), four potential genes were cloned. Three of the expressed proteins EngEF from Enterococcus faecalis, EngPA from Propionibacterium acnes, and EngCP from Clostridium perfringens were purified and characterized. Their substrate specificity was investigated and compared to the commercially available endo-al...
متن کاملProduction of α - Glucosidase Inhibitor by β - Glucosidase Inhibitor - Producing
A soil microorganism producing αand β-glucosidase inhibitors was identified as Bacillus lentimorbus, based on the fatty acid and morphological analyses, along with biochemical and physiological tests. The α-glucosidase inhibitor was highly produced by this strain in a culture medium containing 0.25% of sodium glutamate and 0.5% of glucose, pH 8.0 at 30C for 2 days. The α-glucosidase inhibitor f...
متن کاملPurification, characterization, and substrate specificity of a novel highly glucose-tolerant beta-glucosidase from Aspergillus oryzae.
Aspergillus oryzae was found to secrete two distinct beta-glucosidases when it was grown in liquid culture on various substrates. The major form had a molecular mass of 130 kDa and was highly inhibited by glucose. The minor form, which was induced most effectively on quercetin (3,3',4',5,7-pentahydroxyflavone)-rich medium, represented no more than 18% of total beta-glucosidase activity but exhi...
متن کاملSubstrate specificity analysis of endoplasmic reticulum glucosidase II using synthetic high mannose-type glycans.
Glucosidase II (Glc'ase II) is a glycan-processing enzyme that trims two alpha1,3-linked Glc residues in succession from the glycoprotein oligosaccharide Glc2Man9GlcNAc2 to give Glc1Man9GlcNAc2 and Man9GlcNAc2 in the endoplasmic reticulum (ER). Monoglucosylated glycans, such as Glc1-Man9GlcNAc2, generated by this process play a key role in glycoprotein quality control in the ER, because they ar...
