Purification and properties of angiotensin-converting enzyme from hog lung.
Angiotensin-converting enzyme was purified 1500-fold from a homogenate of hog lungs. The purification procedure included fractionation with ammonium sulfate, inactivation of contaminating enzymes at pH 4.7, batch treatment with CM-cellulose, and chromatography on columns of DEAE-cellulose, hydroxyapatite, and Sephadex G-200. The enzyme was assayed with hippurylglycylglycine and, after pH 4.7 wa...

متن کاملextraction 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 اولPurification and properties of tyrosine-activating enzyme of hog pancreas.
Activation reactions of this type are catalyzed by enzymes from various sources (2-6) and specific activating enzymes may be required for each amino acid (2). The first highly purified, activating enzyme was a tryptophan-activating enzyme from beef pancreas, studied by Davie et al. (7). The isolation and properties of a tyrosine-activating enzyme from hog pancreas (8) are described in this report.
متن کاملPurification and properties of the aldehyde oxidases from hog and rabbit livers.
The aldehyde oxidases from rabbit and hog livers have been purified to homogeneity by modifications of and additions to previously published procedures. The final preparations were judged to be homogeneous on the basis of ultracentrifugal, electrophoretic, chromatographic, spectral, and kinetic criteria. A number of physical and kinetic properties of the homogeneous enzymes have been determined...
