For both molecules, a molar mass of 44,500±4,000 was determined from small angle X-ray scattering as well as from dynamic light scattering. The shape parameters of the two rRNAs, volume V c, surface O c, radius of gyration R s, maximum dimension of the molecule L, thickness D, and cross section radius of gyration R sq, agree within the experimental error limits. The mean values are V c=57±3 nm3, O c=165±10 nm2, R s=3.37±0.05 nm, L=10.8±0.7 nm, D=1.57±0.07 nm, R sa=0.92±0.01 nm. Identical structures for the E. coli 5S rRNA and the rat liver 5S rRNA at a resolution of 1 nm can be deduced from this agreement and from the comparison of experimental X-ray scattering curves and of experimental electron distance distribution function. The flat shape model derived for prokaryotic and eukaryotic 5S rRNA shows a compact region and two protruding arms. Double helical stems are eleven-fold helices with a mean base pair distance of 0.28 nm. Combining the shape information obtained from X-ray scattering with the information about the frictional behaviour of the molecules, deduced from the diffusion coefficients D 20,w 0 =(5.9±0.2)·10-7 cm2s-1 and (6.2±0.2)·10-7 cm2s-1 for rat liver 5S rRNA and E. coli 5S rRNA, respectively, a solvation shell of about 0.3 nm thickness around both molecules is determined. This structural similarity and the consensus secondary structure pattern derived from comparative sequence analyses suggest that all 5S rRNAs may indeed have conserved essentially the same type of folding of their polynucleotide strands during evolution, despite having very different sequences.Type of Medium: Electronic ResourceURL: -

ISSN: 0006-3525Keywords: Chemistry ; Polymer and Materials ScienceSource: Wiley InterScience Backfile Collection 1832-2000Topics: Chemistry and PharmacologyNotes: It was shown by viscometric measurements that a tropocollagen solution at low shear gradients manifests elastic features which can be connected only with the existence of a labile spatial structure which develops in time in the solution. To judge by the concentration dependence of the rate of formation of this structure, it does not represent a molecular net formed by direct contact of macromolecules. Most likely this structure is a result of stabilization of macromolecules at a certain distance from each other. The study of light scattering by tropocollagen solutions demonstrated that it does not correspond with the scattering by rigid rod-shaped units. Anomalies in the character of light scattering are probably the result of intermolecular interference produced by a spatial supermolecular structure and, in turn, indicate that this structure is to some extent regular. In the presence of salts the elastic features in the tropocollagen solution and anomalies in light scattering disappear in a narrow range of temperatures immediately before the process of denaturation which makes it possible to conclude that the supermolecular regular structure is disrupted in this temperature range.Additional Material: 16 Ill.Type of Medium: Electronic ResourceURL: -

ISSN: 0006-3525Keywords: Chemistry ; Polymer and Materials ScienceSource: Wiley InterScience Backfile Collection 1832-2000Topics: Chemistry and PharmacologyNotes: The urea-induced unfolding of 16S RNA at low ionic strength has been studied by dynamic light scattering, uv spectroscopy, and some hydrodynamic methods. Three components could be resolved in the photon correlation spectra of scattered light, using the inverse Laplace transform SIPP program [G. R. Danovich and I. N. Serdyuk (1983) in Photon Correlation Techniques in Fluid Mechanics, vol. B38, E. O. Schulz-Dubois, Ed., Springer, Berlin/Heidelberg, New York, p. 315]. One component is assigned to the center-of-mass translation of the RNA, another one to a combination of translational and internal motion, and the last to diffusion of urea clusters. The hydrodynamic dimensions of RNA increase strongly upon transition from 4 to 6M urea. We conclude that up to 2M urea, 16S RNA is highly elongated, and coiled above 4M urea, with a great increase of the hydrodynamic dimensions of RNA being observed upon transition from 4 to 6M urea. A scheme for RNA unfolding is proposed. © 1993 John Wiley & Sons, Inc.Additional Material: 7 Ill.Type of Medium: Electronic ResourceURL: -

ISSN: 0006-3525Keywords: Chemistry ; Polymer and Materials ScienceSource: Wiley InterScience Backfile Collection 1832-2000Topics: Chemistry and PharmacologyNotes: The resolving ability of the SIPP program operating on the regularzation principle was studied in computer experiments and in real experiments on a mixture of particles was two different dimensions as well as on tobacco mosaic virus. It has been shown that the limit of resolution in real dynamic light scattering experiments is achieved when the ratio of the characteristic times of the components is 1:2, provided that the contribution of the “slow” component to scattering is about twice that of the “fast” component.Some practical rules that serve to obtain the best resolution of the two compnoents have been formulated.Additional Material: 4 Ill.Type of Medium: Electronic ResourceURL: -
