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 اولEnzymes of the Glyoxylate Cycle in Germinating From the Plant Peanuts and Castor Beans
of conversion of fat to carbohydrate in germinating castor beans. Of the four requisite enzymes, isocitritase (Equation 3) has been demonstrated by direct assay (l), while the presence of condensing enzyme (Equation 1), aconitase (Equation 2), and malate synthetase activity (Equation 4) has been inferred from isotope incorporation data. The rates of condensing enzyme and malate synthetase, as e...

composed of all the valence electrons of the specimen. In this case, the electrons of the metal are coupled via the photon gas; their actions are not completely independent. Such a situation is not the case in the usual photosynthetic system; equilibrium or quasiequilibrium ideas may not be applied. In this situation each photosynthetic event is completely independent of the other events taking...

متن کاملPyruvate Dehydrogenase Complex from Germinating Castor Bean
Subceliular organelles from castor bean (Ricuns commnwuis) endosperm were isolated on discontinuous sucrose gradients from germinating seeds which were 1 to 7 days postbit o. Marker enzyme activities of the organeUes were measured (fumarase, catalase, and triose phosphate isomerase) and the homogeneity of the organelle fractions was examined by electron microscopy. Pyrumate dehydrogenase comple...
