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 کاملRole of a PA14 domain in determining substrate specificity of a glycoside hydrolase family 3 β-glucosidase from Kluyveromyces marxianus.
β-Glucosidase from Kluyveromyces marxianus (KmBglI) belongs to the GH3 (glycoside hydrolase family 3). The enzyme is particularly unusual in that a PA14 domain (pf07691), for which a carbohydrate-binding role has been claimed, is inserted into the catalytic core sequence. In the present study, we determined the enzymatic properties and crystal structure of KmBglI in complex with glucose at a 2....
متن کاملThe β-Glucosidase of the Yeast Cell Surface
There are two distinct components of the system which limits the rate at which intact cells of S. cerevisiae C hydrolyze external beta-glucosides; one component requires metabolic energy and the other is stereospecific for beta-glucosides. The stereospecific component is localized at the cell membrane, as shown by its sensitivity to heavy metal inhibitors which did not penetrate the cell under ...
