Potential Target

Acinetobacter baumanniiis a common multidrug-resistant clinical pathogen that is often found in hospitals. TheA. baumanniiphosphoglycerate kinase (AbPGK) is involved in the key energy-producing pathway of glycolysis and presents a potential target for antibiotic development.AbPGK has been expressed and purified; it was crystallized using lithium sulfate as the precipitant. TheAbPGK crystals belonged to space groupP2221. They diffracted to a resolution of 2.5 Å using synchrotron radiation at the Canadian Light Source.

Increasing Temperature

AbstractTemperature dependent Raman spectroscopic studies of single crystal lithium sulfate are summarized. Coupling between sulfate ion bending modes and the lithium ion translatory modes becomes weaker with increasing temperature until the lithium modes can no longer be observed above 250° C. The temperature interval above 450° in the monoclinic phase is marked by the onset of significant sulfate ion reorientational motion, as evidenced by the bandshape studies of the sulfate ion v1, mode and the librational modes. Bandshape analysis of the v3mode in the plastic phase strongly suggests that the symmetry of the sulfate ion potential energy environment has planar anisotropy.The lithium ion-sulfate ion interactions are modeled for correlated sulfate ion configurations as a function of lithium ion position. The results support the role of the octahedral site in lithium ion transitions contributing to the ionic conductivity.

ABSTRACT By means of modeling experiments on a wax slab, oil-coupled lithium sulfate transducers are found to have excellent directional properties as seismic modeling transducers. Investigation of the several orders of multiple reflection amplitudes shows that consistency in the measured reflection coefficients for the spherical wave fronts is easily achieved if a loss mechanism of the internal viscosity type is attributed to the wax.
