  • Structural investigations to understand the mechanisms of two proteins involved in sulfur chemistry : SsuE and cysteine dioxygenase

    Creator:
    Driggers, Camden McCullough
    Abstract:
    Sulfur is one of the six elements required during the early stages of the evolution of life, and enzymes involved in sulfur transfer and oxidation are increasingly being recognized as potential drug targets for antimicrobials as well as for therapies for cancer, neurodegenerative and inflammatory diseases. Bacteria are able to...

  • Structural Insights into Novel Sugar Phosphate Cyclases and Flavoenzymes

    Creator:
    Kean, Kelsey M.
    Abstract:
    The function of a protein is defined by its three-dimensional structure, and in understanding the three-dimensional structure of a protein, we gain an understanding of its function and mechanism. Protein structures, especially at high resolution, can provide detailed insights into many elements of enzyme function and catalysis – identifying residues...

  • Model systems for structural investigations into peroxiredoxin catalysis, conformation change, and inactivation

    Creator:
    Perkins, Arden
    Abstract:
    Peroxiredoxin (Prx) enzymes catalyze the reduction of hydrogen peroxide, peroxynitrous acid, and organic peroxides, and are extremely efficient peroxidases, with k[subscript cat]/K[subscript M] on the order of 10⁷ - 10⁸ M⁻¹ s⁻¹. Besides their role in oxidative stress defense, evidence has accumulated that some eukaryotes, including humans, use Prxs as...

  • Exploring Protein Structure: Seeing the Forest and the Trees

    Creator:
    Brereton, Andrew E.
    Abstract:
    Life on Earth intimately depends on the function of countless proteins. For the majority of studied proteins, function absolutely depends on conformation (i.e. 3-dimensional shape in solution). The exact nature of how a protein goes from an unfolded linear polypeptide chain to an organized folded molecule is still not known,...

  • Biophysical analyses of peroxiredoxins and a partner reductase

    Creator:
    Hall, Andrea Renée
    Abstract:
    Peroxiredoxins (Prxs) are dominant peroxide-reducing enzymes with two important roles: they protect all organisms from oxidative damage induced by peroxides, and in eukaryotes, they participate in hydrogen peroxide signaling pathways. This dissertation presents studies aimed at the biophysical characterization of select Prxs and a Prx reductase to elucidate their structure-function...
