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 اولStructure and properties of malic enzyme from Bacillus stearothermophilus.
The malic enzyme (EC 1.1.1.38) gene of Bacillus stearothermophilus was cloned in Escherichia coli, and the enzyme was purified to homogeneity from the E. coli clone. In addition to the NAD(P)-dependent oxidative decarboxylation of L-malate, the enzyme catalyzes the decarboxylation of oxalacetate. The enzyme is a tetramer of Mr 200,000 consisting of four identical subunits of Mr 50,000. The pH o...

15 صفحه اولsome properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
