Our research program is based on a combination of organic chemistry, biochemistry, and biophysics directed towards understanding the various roles small molecules play in redox biochemistry. We are especially interested in how nitric oxide (NO), hydrogen sulfide (H2S) and hydrogen peroxide (H2O2), and nitroxyl (HNO) affect bacteria that produce structurally unique low molecular weight (LMW) thiols. Nitroxyl and hydrogen sulfide regulate sulfur metabolism in bacteria and our current interests focus on the investigation of reactivity of nitroxyl with the unique low molecular weight thiols found in some bacteria. We currently study the in vitro reactions of nitroxyl with bacillithiol and mycothiol to determine the reaction kinetics and products. The effect of nitroxyl on the bacteria producing these thiols will be related to the in vitro chemistry and the observed phenotype. We are also improving the total syntheses of bacillithiol and mycothiol to produce more compounds for study and generating analogs of these compounds that could find use as antibiotics. We also work to further refine our methods of HNO detection. Many of these projects are completed in collaboration with other groups in chemistry, physics and the medical school. Students in our group are exposed to organic synthesis, biochemistry, molecular biology, biophysics (especially spectroscopy) and bio-analytical chemistry.
