A. Summary

This research program encompasses studies of model hemes and heme proteins, which are studied by spectroscopic methods of various kinds, with the aim of determining electronic structure, bonding, thermodynamics and kinetics of hemes and other metallomacrocycles. Early work involved investigations of synthetic hemes and other metallomacrocycles by multidimensional NMR spectroscopy, metal nucleus NMR spectroscopy, continuous wave and pulsed EPR spectroscopy, electronic, low temperature MCD, Mössbauer and PES spectroscopies, binding of small molecules to hemes and heme proteins, and electrochemistry of metallomacrocycle complexes. In recent years we have concentrated mainly on heme proteins, including nitrosylheme proteins, particularly the nitrophorins of Rhodnius prolixus, the electron-transferring cytochromes, especially the cytochrome bc1 complexes from yeast and bacteria, and cytochromes P450 and their enzymatic reactions. We use gene synthesis, or site-directed mutagenesis on existing genes, and bacterial expression of heme proteins, to create mutant proteins which will answer important questions regarding the mechanism of action of important biomolecules.
