Journal ArticleDOI
Effect of alcohol on the properties of micellar systems. V. Small angle neutron scattering study
Raoul Zana,C. Picot,R. Duplessix +2 more
TL;DR: In this paper, small angle neutron scattering (SANS) was used to characterize the micelles of tetradecyltrimethylammonium bromide (t-TTAB) in 0.1 M KBr aqueous solutions, with or without added 1-pentanol.
Journal ArticleDOI
Molecular Crowding Favors Reactivity of a Human Ribozyme Under Physiological Ionic Conditions
TL;DR: In this paper, a self-cleavage reaction of human hepatitis delta virus-like CPEB3 ribozyme in the background of physiological ionic concentrations and various crowding and cosolute agents was studied.
Journal ArticleDOI
Structure, mechanism and ensemble formation of the alkylhydroperoxide reductase subunits AhpC and AhpF from Escherichia coli
Phat Vinh Dip,Neelagandan Kamariah,Malathy Sony Subramanian Manimekalai,Wilson Nartey,Asha Manikkoth Balakrishna,Frank Eisenhaber,Birgit Eisenhaber,Gerhard Grüber +7 more
TL;DR: A novel overall mechanistic model of AhpR as a hydroperoxide scavenger is suggested, in which the dimeric, extended AhpF prefers complex formation with the AhpC ring to accelerate the catalytic activity and thus to increase the chance of rescuing the cell from ROS.

A model for the dimeric molecular structure of phytochrome based on small-angle X-ray scattering
Satoru Tokutomi,Masayoshi Nakasako,Jun Sakai,Mikio Kataoka,Kotaro T. Yamamoto,Masamitsu Wada,Fumio Tokunaga,Masaki Furuya +7 more
TL;DR: In this paper, the structure of pea phytochrome in the red-light-absorbing form was studied with reference to the structures of its molecular domains in a monomer (an N-terminal 59-kDa chromophoric domain and a Cterminal 55-kda non-chromophoric domains) using small-angle X-ray scattering, and a four-leaved shape model was proposed.
Journal ArticleDOI
Tuning Riboswitch Regulation through Conformational Selection
TL;DR: A comprehensive model of the structural, thermodynamic, and functional properties of this compact RNA regulatory element is presented.

Statistical Mechanics of Fluid Mixtures
TL;DR: In this paper, the chemical potentials of the components of gas mixtures and liquid solutions are obtained in terms of relatively simple integrals in the configuration spaces of molecular pairs, and the molecular pair distribution functions appearing in these integrals are investigated in some detail, in their dependence upon the composition and density of the fluid.

The optical principles of the diffraction of x-rays.
TL;DR: In this paper, Bragg et al. describe the Optik der R6ntgenstrahlen in Raumgitter and leitet damit fiber zu den experimentellen Methoden and Ergebn]ssen, die den folgenden B~nden vorbehalten bleiben.

Small-Angle X-Ray Scattering
W. Ehrenberg,A. Franks +1 more
TL;DR: The neighbourhood of the direct beam is, for a variety of reasons, easily obscured by scattered radiation and insufficient collimation, so that special measures such as very long film-specimen distances or focusing crystal monochromators have been used for obtaining satisfactory photographs.
