Escherichia coli RNA polymerase-associated SWI/SNF protein RapA: evidence for RNA-directed binding and remodeling activity |
| Journal |
Nucleic Acids Res, 2007;35:1-17, McKinley BA, Sukhodolets MV
|
| Description |
Helicase-like SWI/SNF proteins are present in organisms belonging to distant kingdoms from bacteria to humans, indicating that they perform a very basic and ubiquitous form of nucleic acid management; current studies associate the activity of SWI/SNF proteins with remodeling of DNA and DNA–protein complexes. This work presents evidence that RapA - the bacterial homolog of eukaryotic SWI/SNF proteins - binds and remodels RNA during transcription

The externally derived portion of the hyperosmotic shock-activated cytosolic calcium pulse mediates adaptation to ionic stress in suspension-cultured tobacco cells |
| Journal |
J Plant Physiol, 2007;164: 815-823, Cessna SG, Matsumoto TK, Lamb GN, Rice SJ, Hochstedler WW
|
| Description |
The influx of calcium into the cytosol has long been suggested to serve as a signaling intermediate in the acquisition of tolerance to hyperosmotic and salinity stresses in plant cells, but the cellular origins (e.g. organelle release or externally-derived influx) of the calcium entering the cytosol have been disputed. Using tobacco cells that were stably transformed to express the cytosol-localized Ca2+-sensitive bioluminescent protein aequorin, we demonstrate that hyperosmotic stress initiates a cytosolic calcium signal deriving from both the release of organellar calcium and the entry of extracellular calcium. Using selective calcium signaling inhibitors, the externally-derived portion of this calcium signal was subsequently shown to be critical in ionic stress acquisition in these cells

Substituent effects on the relative electronic energies of pyrrole and the imine tautomers of pyrrole |
| Journal |
J Undergrad Chem Res, 2007;6:119-128, Wilson WR, Ligare MR, Codding SJ, Berumen JM, Zoellner RW

| Description |
Hartree-Fock computational methods were used to determine the structures and properties of twenty-three tetra-substituted pyrroles in order to determine the effect of ring substituents on the relative energies of the pyrrole tautomers and the cyclic imine (azadiene) tautomers. When tetra-substituted with either fluoro-, hydroxy-, methoxy-, amino-, dimethylamino-, nitro-, or vinyl-substituents, the azadiene tautomer is predicted to be more stable than the pyrrole tautomer

Characteristics of aggregation induced emission in 1,1-dimethyl-2,3,4,5-tetraphenyl and 1,1,2,3,4,5-hexaphenyl siloles and germoles |
| Journal |
J Inorg Organomet P, 2007;17:201-213, Mullin JL, Tracy HJ, Ford JR, Keenan SR, Fridman F
|
| Description |
A comparative study of the dramatic aggregation-induced enhancement (AIE) of luminescence exhibited by a set of four metalloles (two siloles and two germoles) was undertaken in an effort to characterize this unusual behavior and gain insights into it origins. All four of the compounds studied showed increases in luminescence quantum yields of approximately two orders of magnitude in aggregated states, compared to unaggregated states in solution. The characteristics of this behavior point to restricted intramolecular rotations within the propeller-shaped molecules as the primary cause of the dramatic increase in luminescence of the aggregates. This was an invited paper in a special issue of JIOPM in honor of Professor Ian Manners

Reverse selectivity in m-CPBA oxidation of oligothiophenes to sulfones |
| Journal |

|
| Description |
Oligothiophene sulfones of up to six rings can be conveniently prepared by the direct oxidation of butyl-substituted thiophene oligomers with m-CPBA in dichloromethane. Reverse selectivity of oxidized rings is observed relative to previously reported systems without alkyl-substitution. Thiophene-based sulfones (or S,S-dioxides) are an important class of organic materials for a variety of applications including opto-electronic devices and biodiagnostics. This research was a collaborative effort between several institutions

Dynamics of water in carbon tetrachloride |
| Journal |
J Phys Chem A, 2007;111:6146-6150, Goodnough JA, Goodrich L, Farrar TC
|
| Description |
A dilute solution of water in a hydrophobic solvent, such as carbon tetrachloride (CCl4), presents an opportunity to study the rotational properties of water without the complicating effects of hydrogen bonds. We reported the results of theoretical, experimental, and semiempirical studies of a 0.03 mole percent solution of water in CCl4. It was shown that for this solution there are negligible water-water interactions or water-CCl4 interactions; theoretical and experimental values for proton NMR chemical shifts are used to confirm the minimal interactions between water and the CCl4. The average correlation time (time for the vector to rotate one radian) for the position vector of 17O in monomer water is 91 fs. The average value for the deuterium correlation time for the deuterium vector (along the OD bond) is 104 fs. Jennifer Goodnough is a professor of chemistry

A series of triorganotin 2,2,3,3-tetramethylcyclopropanecarboxylates, where R = methyl, ethyl, n-propyl, n-butyl, phenyl and cyclo-hexyl, were synthesized. Structural characterization by several spectroscopic techniques indicated that all the complexes with the exception of the four-coordinated tricyclohexyl compound were five-coordinated in the solid state. In solution, all the complexes were four-coordinated. Larvicidal activities of the complexes were effective against three species of mosquito larvae.

| Description |
This article describes the successful development and implementation of a laser ablation source-equipped Fourier transform microwave spectrometer capable of observing 4 GHz regions of spectra in a single data acquisition event. The dramatically increased speed with which regions may be searched, when compared to other high resolution microwave techniques, allows the source conditions to be the prime variable in laser ablation microwave spectroscopic studies. A second feature of the technique is that observed spectral features have correct relative intensities

| Description |
A simple procedure for the intermolecular homocoupling of arenediazonium salts in air using a catalytic amount of palladium acetate was developed. The optimum conditions were found to be 15 mol% palladium acetate in refluxing methanol, with no additional terminal reducing agent required. These optimized conditions were used to prepare biaryls from several arenediazonium tetrafluoroborate salts, and most examples proceeded in moderate to high yields

Substrate specificity of Fpg (MutM) and hOGG1, two repair glycosylases |
| Journal |
J Amer Chem Soc, 2007;129:7724 – 7725, Hamm ML, Gill TJ, Nicolson SC, Summers MR
|
| Description |
The E.coli and human enzymes Fpg and hOGG, respectively, repair the prominent and promutagenic DNA lesion 8-oxo-2’-deoxyguanosine (OdG). OdG differs from dG (an inactive substrate) at only two positions, N7 and C8; thus the importance of either of these sites to substrate recognition by these enzymes has long been questioned. In this study, three analogues of OdG that varied at N7 and/or C8 were found to be active with either enzyme indicating that substrate recognition is based more on the absence of a clashing co-planer lone pair at N7 (present in dG) and less on the presence of a specific enzyme interaction with OdG

| Description |
Cases in which functional groups form distinct phases are common in material science in general and specifically in polymer and surfactant sciences. To calculate the van der Waals forces associated with such phases, the refractive index of the phases must be evaluated. We have a method to estimate the refractive index of ‘functional group phases’ and discuss how to use these estimations to calculate the associated interaction energies and thereby modify the total calculated van der Waals forces
