Research Summary

Our lab studies signal transduction proteins that are reversibly phosphorylated. Our main focus is CheY, which changes the rotation of bacterial flagellar motors. We chemically modify CheY to mimic phosphorylation, and our goal is to crystallize phosphono-CheY alone and in complexes with other proteins. We have also modified VHR protein phosphatase to mimic the intermediate cysteinyl phosphate. We have synthesized analogs of aspartyl phosphate, including phosphonates, to inhibit aspartate semialdehyde dehydrogenase. We have described a way to teach Michaelis-Menten kinetics through a computer tutorial. We are examining current ways to purify biodiesel.
