Mode of operation and low-resolution structure of a multi-domain and hyperthermophilic endo-β-1,3-glucanase from Thermotoga petrophila.

TL;DR: A comprehensive functional characterization and low-resolution structure of a hyperthermophilic laminarinase from Thermotoga petrophila (TpLam) is described and enzymatic mode of operation is determined, which specifically cleaves internal β-1,3-glucosidic bonds.
Journal ArticleDOI
Thermal alterations in archaeological bones
TL;DR: In this article, it was determined that the studied human bones were treated at three different temperatures close to 100, 250 and 600°C, and they were either boiled (barbacoa) or grilled.
Journal ArticleDOI
Experimental and theoretical studies of plasmon?molecule interactions
TL;DR: This review aims to outline recent progress in experimental practice and theory for probing and exploiting the subtle coupling between discrete molecular orbitals and continuous metallic bands.
Journal ArticleDOI
The effects of small molecule organic additives on the self-assembly and rheology of betaine wormlike micellar fluids.
Thomas M. McCoy,Joshua P. King,Jackson E. Moore,Veena T. Kelleppan,Anna Sokolova,Liliana de Campo,Madhura Manohar,Tamim A. Darwish,Rico F. Tabor +8 more
TL;DR: The findings emphasise the significant impact of impurities or additives on the properties of aqueous wormlike micellar systems formed by zwitterionic surfactants, and could also inform selection of solutes for controlling fluid rheology.
Journal ArticleDOI
Small-angle x-ray scattering studies of calmodulin mutants with deletions in the linker region of the central helix indicate that the linker region retains a predominantly .alpha.-helical conformation
TL;DR: Each protein appears to undergo a transition from a dumbbell shape to a more globular conformation on binding melittin in the presence of calcium, although quantitatively the changes in the wild-type and Des4 proteins greatly exceed those in Des2.

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.
