Comparative Analysis of Β- Glucosidases Thermostability: Differences in Amino Acids Composition and Distribution among Mesostable and Thermostable Β- Glucosidases
Out of various industrial enzymes, thermostable βglucosidases are of great interest, due to their utility in conversion of lingocellulosic material into bioethanol. Determination of the factors responsible for thermostability in β-glucosidases by sequence and structure comparison will be useful in identification, isolation and design of novel thermostable βglucosidases. In the present study the...
متن کاملCharacterization of digestive α- and β-glucosidases in the midgut of Plagiodera versicolora Laicharting (Coleoptera: Chrysomelidae)
سوسک برگخوار بید Plagiodera versicolora یکی از آفات مهم درختان جنگلی در دنیا از جمله ایران میباشد. در پژوهش حاضر، فعالیت آلفا و بتا- گلوکوزیداز در معده میانی حشره کاملP. versicolora بررسی شد. نتایج نشان داد که فعالیت آلفا- گلوکوزیداز بیشتر از بتا-گلوکوزیداز بود. pH بهینه برای فعالیت آلفا و بتا- گلوکوزیداز بهترتیب 6 و 9 بهدست آمد. همچنین دمای بهینه فعالیت این دو آنزیم بهترتیب 30 و 25 درجه...
متن کاملThree-dimensional structures of two heavily N-glycosylated Aspergillus sp. family GH3 β-D-glucosidases.
The industrial conversion of cellulosic plant biomass into useful products such as biofuels is a major societal goal. These technologies harness diverse plant degrading enzymes, classical exo- and endo-acting cellulases and, increasingly, cellulose-active lytic polysaccharide monooxygenases, to deconstruct the recalcitrant β-D-linked polysaccharide. A major drawback with this process is that th...
متن کاملWhen substrate inhibits and inhibitor activates: implications of β-glucosidases
BACKGROUND β-glucosidases (BGs) catalyze the hydrolysis of β-glycosidic bonds in glucose derivatives. They constitute an important group of enzymes with biotechnological interest like supporting cellulases in degradation of lignocellulose to fermentable sugars. In the latter context, the glucose tolerant BGs are of particular interest. These BGs often show peculiar kinetics, including inhibitor...
متن کاملCharacteristics and potential use of β-glucosidases from Zygomycetes
β-Glucosidases (β-D-glucoside glucohydrolases) play important role in nature, including the degradation of cellulosic biomass by fungi and bacteria, breakdown of glycolipids in mammalian lysosomes, and the cleavage of glycosylated flavonoids in plants. These enzymes have broad substrate specificity, and are used in a range of biotechnological processes. The most intensively studied area of thei...
