B. Protein Structure Determination
Stacks Image 2069
Following undergraduate work with Fred Richards on the structure determination of Ribonuclease-S, I decided to pursue a PhD with Joe Kraut at UCSD in protein crystallography. I developed an interest in redox protein structure for my PhD thesis and continued studies on redox proteins during my academic career at UAZ. Subsequently, I have used protein crystallography as a means of investigating a number of questions in structural biology and drug discovery, ranging over the majority of my academic and professional career.

While a graduate student at UCSD in Joe Kraut's lab, I formed a relationship with Martin Kamen who was working on the cytochromes of photosynthetic bacteria. Cytochrome c2 from R. rubrum showed homology with mammalian cytochrome c, but at that time it was unclear if the proteins were structurally related as well. In the event, it was found that the R. rubrum structure was quite similar to the horse cytochrome structure done by Dick Dickerson, then at CalTech.

Following a move to the University of Arizona, I continued working of microbial cytochrome structures being studied in Mike Cusanovich's lab. Cytochrome c' turned out to be a prototypical 4-alpha-helical bundle protein. Numerous cytochrome c' structures have subsequently been determined using X-ray crystallography, although the specific function of the protein remains unknown.

This work was the result of a collaboration with Harold Scheraga. Harold had demonstrated that ribonuclease incorporating an additional chemical cross-link was stabilized, an effect attributed to an entropy decrease in partially unfolded states of the protein. The structure determination demonstrated that the folded state of the chemically modified protein was essentially identical to the native protein structure.
