The Targeting Of The Attoc159 Preprotein Receptor To The Chloroplast Outer Membrane Is Mediated By Its Gtpase Domain And Is Regulated By Gtp, Matthew D. Smith, Andreas Hiltbrunner, Felix Kessler, Danny J. Schnell

Biology Faculty Publications

The multimeric translocon at the outer envelope membrane of chloroplasts (Toc) initiates the recognition and import of nuclear-encoded preproteins into chloroplasts. Two Toc GTPases, Toc159 and Toc33/34, mediate preprotein recognition and regulate preprotein translocation. Although these two proteins account for the requirement of GTP hydrolysis for import, the functional significance of GTP binding and hydrolysis by either GTPase has not been defined. A recent study indicates that Toc159 is equally distributed between a soluble cytoplasmic form and a membrane-inserted form, raising the possibility that it might cycle between the cytoplasm and chloroplast as a soluble preprotein receptor. In the present …

Glutamine Uptake By Neurons: Interaction Of Protons With System A Transporters, Farrukh A. Chaudhry, Dietmar Schmitz, Richard J. Reimer, Peter Larsson, Andrew T. Gray, Roger Nicoll, Michael Kavanaugh, Robert H. Edwards

Biomedical and Pharmaceutical Sciences Faculty Publications

Astrocytes provide the glutamine required by neurons to synthesize glutamate and GABA. However, the mechanisms involved in glutamine transfer from glia to neurons have remained poorly understood. Recent work has implicated the System N transporter SN1 in the efflux of glutamine from astrocytes and the very closely related System A transporters SA1 and SA2 in glutamine uptake by neurons. To understand how these closely related proteins mediate flux in different directions, we have examined their ionic coupling. In contrast to the electroneutral exchange of H⁺ for Na⁺ and neutral amino acid catalyzed by SN1, we now show that …

Dynamic Equilibrium Between Coupled And Uncoupled Modes Of A Neuronal Glutamate Transporter, Lars Borre, Michael Kavanaugh, Baruch I. Kanner

Biomedical and Pharmaceutical Sciences Faculty Publications

In the brain, the neurotransmitter glutamate is removed from the synaptic cleft by (Na⁺ + K⁺)-coupled transporters by an electrogenic process. Moreover, these transporters mediate a sodium- and glutamate-dependent uncoupled chloride conductance. In contrast to the wild type, the uptake of radiolabeled substrate by the I421C mutant is inhibited by the membrane-impermeant [2-(trimethylammonium)ethyl]methanethiosulfonate and also by other sulfhydryl reagents. In the wild-type and the unmodified mutant, substrate-induced currents are inwardly rectifying and reflect the sum of the coupled electrogenic flux and the anion conductance. Remarkably, the I421C mutant modified by sulfhydryl reagents exhibits currents that are non-rectifying …

Use Of Pyrolysis Gc/Ms For Predicting Emission Byproducts From The Incineration Of Double-Base Propellant, Donald Cropek, Patricia Kemme, Jean Day, Jane Cochran

United States Army: Publications

Gas chromatography/mass spectrometry was used to analyze the pyrolytic byproducts from an Army-unique propellant compound (AA2) that is composed of predominantly nitrocellulose and nitroglycerin. Compounds produced by AA2 pyrolysis were compared to compounds detected in the gaseous effluent from AA2 incineration. The light permanent gases and most of the higher molecular weight byproducts produced by AA2 incineration are replicated by laboratory pyrolysis on AA2. The reverse case also holds whereby 18 out of 24 high molecular weight AA2 pyrolytic byproducts are found in the incinerator emissions. Poor matching, however, was obtained between the two processes for the volatile, water-soluble species. …

A Multiple Regression Analysis Of Selected Variables Effecting The Transmission Of Video Over Internet Protocol Networks, David A. Rosenthal

All-Inclusive List of Electronic Theses and Dissertations

The goal of this study was to conduct multiple regression analyses of selected variables effecting the transmission of video over Internet Protocol (IP) networks, utilizing data from Peak Signal-to-Noise Ratio (PSNR) and Picture Quality Rating (PQR) measurement metrics. The variables selected for this research were congestion-specific in nature and multiple regression analyses were performed to identify the amount of variance in video signal quality attributable to their combined effects. The foundational research hypothesis constructed for this study proposed that increases in CODEC bit rates and network bandwidth would have no significant effect on the PSNR and PQR levels of transmitted …

Preservice Teachers' Perceptions Of Cultural Competency, N. Diana Ross

All-Inclusive List of Electronic Theses and Dissertations

The purpose of this study was to examine preservice teachers' perceptions of cultural competence during the student teaching experience as the result of participating in a diversity and poverty simulation. The results of this study were consistent with present research on developing cultural competencies and the use of simulations in teacher preparation programs. This qualitative research utilized data gathered through interviews with preservice teachers from a private university, citations from expert sources, and insights from the researcher's twenty-five years of teaching experience. The voices of the preservice teachers in this study evidenced increased cultural awareness as a result of their …
