The primary structure of the basic isoform of Acanthamoeba profilin.
Acanthamoeba profilin-II [Kaiser, D.A., Sato, M., Ebert, R. F. and Pollard, T.D. (1986) J. Cell. Biol. 102, 221-226] was digested with trypsin or cleaved by 2-(2-nitrophenylsulphenyl)-3-methyl-3-bromoindolenine. The tryptic peptides were purified by reversed-phase-high-performance liquid chromatography and completely sequenced using automated gas-phase sequence analysis. The complete profilin-I...
متن کاملReinvestigation of the inhibition of actin polymerization by profilin.
In buffer containing 50 mM KCl, 1 mM MgCl2, 1 mM EGTA, 5 mM imidazole, pH 7.5, 0.1 mM CaCl2, 0.2 mM dithiothreitol, 0.01% NaN3, and 0.2 mM ATP, the KD for the formation of the 1:1 complex between Acanthamoeba actin and Acanthamoeba profilin was about 5 microM. When the actin was modified by addition of a pyrenyl group to cysteine 374, the KD increased to about 40 microM but the critical concent...
متن کاملMechanism of the interaction of human platelet profilin with actin
We have reexamined the interaction of purified platelet profilin with actin and present evidence that simple sequestration of actin monomers in a 1:1 complex with profilin cannot explain many of the effects of profilin on actin assembly. Three different methods to assess binding of profilin to actin show that the complex with platelet actin has a dissociation constant in the range of 1 to 5 mic...

هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...
15 صفحه اولThe amino acid sequence of Acanthamoeba profilin.
The complete amino acid sequence of Acanthamoeba profilin was determined by aligning tryptic, chymotryptic, thermolysin, and Staphylococcus aureus V8 protease peptides together with the partial NH2-terminal sequences of the tryptophan-cleavage products. Acanthamoeba profilin contains 125 amino acid residues, is NH2-terminally blocked, and has trimethyllysine at position 103. At five positions i...
