Mannan-degrading enzymes from Cellulomonas fimi.
The genes man26a and man2A from Cellulomonas fimi encode mannanase 26A (Man26A) and beta-mannosidase 2A (Man2A), respectively. Mature Man26A is a secreted, modular protein of 951 amino acids, comprising a catalytic module in family 26 of glycosyl hydrolases, an S-layer homology module, and two modules of unknown function. Exposure of Man26A produced by Escherichia coli to C. fimi protease gener...

آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...
15 صفحه اولCrystallization and X-ray diffraction studies of cellobiose phosphorylase from Cellulomonas uda.
Disaccharide phosphorylases are able to catalyze both the synthesis and the breakdown of disaccharides and have thus emerged as attractive platforms for tailor-made sugar synthesis. Cellobiose phosphorylase from Cellulomonas uda (CPCuda) is an enzyme that belongs to glycoside hydrolase family 94 and catalyzes the reversible breakdown of cellobiose [beta-D-glucopyranosyl-(1,4)-D-glucopyranose] t...
متن کاملXylan-Degrading Catalytic Flagellar Nanorods.
Flagellin, the main component of flagellar filaments, is a protein possessing polymerization ability. In this work, a novel fusion construct of xylanase A from B. subtilis and Salmonella flagellin was created which is applicable to build xylan-degrading catalytic nanorods of high stability. The FliC-XynA chimera when overexpressed in a flagellin deficient Salmonella host strain was secreted int...
متن کاملCellulose- and xylan-degrading thermophilic anaerobic bacteria from biocompost.
Nine thermophilic cellulolytic clostridial isolates and four other noncellulolytic bacterial isolates were isolated from self-heated biocompost via preliminary enrichment culture on microcrystalline cellulose. All cellulolytic isolates grew vigorously on cellulose, with the formation of either ethanol and acetate or acetate and formate as principal fermentation products as well as lactate and g...
