Carbodiimide modification enhances activity of pig pancreatic phospholipase A2.
Pig phospholipase A2, pig iso-phospholipase A2 and bovine pancreatic phospholipase A2 were reacted in solution with 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide, in the presence of N-hydroxysulfosuccinimide, at pH 7. The influence of micellar protectants was analyzed. In the presence of n-hexadecylphosphocholine, the losses of activity in micellar diheptanoyl-lecithin were 80, 35, and 10% in b...
متن کاملFunctional carboxyl groups in the red cell anion exchange protein. Modification with an impermeant carbodiimide
Anion exchange in human red blood cell membranes was inactivated using the impermeant carbodiimide 1-ethyl-3-(4-azonia-4,4-dimethylpentyl)-carbodiimide (EAC). The inactivation time course was biphasic: at 30 mM EAC, approximately 50% of the exchange capacity was inactivated within approximately 15 min; this was followed by a phase in which irreversible exchange inactivation was approximately 10...
متن کاملbuckling of viscoelastic composite plates using the finite strip method
در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....
Carbodiimide modification analysis of aminoacylated yeast phenylalanine tRNA: evidence for change in the apex region.
The G- and U-specific reagent, carbodiimide was used to probe the solution structure of aminoacylated yeast phenylalanine tRNA. Both quantitative and qualitative changes in modification were observed when the modification patterns of tRNA-CCA(3'OH), tRNA-CCA(3'NH2) and phe-tRNA-CCA(3'NH2) were compared. Five nucleotides were modified in all cases, D16 and G20 in the D-loop, U33 and Gm34 in the ...
متن کاملDirect modification of mRNA by ferrocenyl carbodiimide and its application to electrochemical detection of mRNA.
Ferrocenyl carbodiimide (1) could be used for the direct labeling of synthetic RNA and expressed mRNA in vitro with the electrochemically active ferrocene moieties. These RNAs modified by 1 could be detected electrochemically coupled with a DNA probe-immobilized electrode. After hybridization of 1.1 Kb mRNA modified by 1 with the DNA probe-immobilized electrode, the peak charge observed by an O...
