extraction and acetylation of purified trypsin from bovin pancreas and study of some its physico-chemical properties
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 اولSome properties of purified isocitric enzyme.
2. Throughout purification the ratio of i8ocitricdehydrogenase activity to oxalosuccinic-carboxylase activity remains constant, and inactivation of the one produces a corresponding inactivation ofthe other. 3. Sedimentation and diffusion measurements, and electrophoretic analysis at pH 5-6, 7-3 and 8-5, show that the enzyme is a single protein. It has been obtained 90-95% pure. 4. Further fract...
متن کاملBacteriophage T7 endonuclease. I. Properties of the enzyme purified from T7 phage-infected Escherichia coli B.
An endonuclease activity present in extracts from Escherichia coli B infected with T7f phage has been purified 2500fold. This enzyme, T7 endonuclease I, is the product of gene 3, and its activity is maximal 7.5 min after infection at 37”. The activity is at least 100 times greater with single stranded DNA as substrate than with duplex DNA. The limit product obtained by digestion of single stran...
متن کاملPhysiochemical properties of experimental nano-hybrid MTA
Introduction: Development of new pulp capping agents has paved the way towards the preservation of pulp vitality, which is an important goal in restorative dentistry. This study sought to assess the calcium ion release, pH and setting of mineral trioxide aggregate (MTA) Angelus, an experimental formulation of nano-hybrid MTA containing nano-SiO2, nano-Al2O3 and nano-TiO2 and MTA Angelus plus na...
متن کاملCross-linked Enzyme Aggregates of Catalase from Bovine Liver
Stabilization of multimeric enzymes is one of the major challenges in biocatalysis, because dissociation of subunits can inactivate the enzyme. Catalase (CAT; EC 1.11.16) is a homotetramer containing Fe-protoporphyrin IX in its active site. CAT breaks down hydrogen peroxide into water and molecular oxygen. In this study, crosslinked enzyme aggregates of bovine liver CAT (CAT-CLEAs) were prepare...
