Characteristics of partially purified prolidase and prolinase from the human prostate.
Both prolidase and prolinase from the human prostate were separated into two peaks by TSK DEAE-5PW chromatography. These peaks of prolidase isozymes I and II differed from each other in their responses to preincubation with Mn2+, their substrate specificity, optimal pH, and heat stability. The molecular weights of prolidases I and II were estimated to be 110,000 and 165,000, respectively, by ge...
متن کاملThe Preparation of Partially Purified
The treatment of tuberculous meningitis is frequently hindered by the formation of exudate within the cerebrospinal spaces. This exudate may obstruct the cerebrospinal circulation and give rise to the complications of subtentorial, basal cistern, and spinal block. Furthermore, the presence of exudate predisposes to the occurrence of tuberculous arteritis, which is responsible for the cerebral a...

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 اولProperties of deoxycytidine kinase partially purified from L1210 cells.
A kinase that catalyzes the phosphorylation of deoxycytidine has been purified 150-fold from L1210 murine leukemia cells. The reaction requires a divalent cation (preferably Mg++ or Mn++) and a nucleoside triphosphate. Optimal activity was obtained with ATP. Phosphorylation of deoxycytidine was competitively inhibited by both proximal (dCMP) and distal (dCDP and dCTP) end products and by cytosi...
متن کاملProperties of deoxythymidine kinase partially purified from animal tumors.
The activity of deoxythymidine kinase appears related to the proliferative ability of the cell (l-6). In adult rat liver, deoxythymidine kinase activity is virtually undetectable but appears rapidly during liver regeneration (I, 5, 7-10); the enhancement in the latter case is completely blocked by X-irradiation (II). Deoxythymidine kinase activity is also markedly enhanced in the livers of rats...
