520 3 |a Sulfite-oxidizing enzymes (SOEs) are molybdenum enzymes that exist in almost all forms of life where they carry out important functions in protecting cells and organisms against sulfite-induced damage. Due to their nearly ubiquitous presence in living cells, these enzymes can be assumed to be evolutionarily ancient, and this is reflected in the fact that the basic domain architecture and fold structure of all sulfite-oxidizing enzymes studied so far are similar. The Mo centers of all SOEs have five-coordinate square pyramidal coordination geometry, which incorporates a pyranopterin dithiolene cofactor. However, significant differences exist in the quaternary structure of the enzymes, as well as in the kinetic properties and the nature of the electron acceptors used. In addition, some SOEs also contain an integral heme group that participates in the overall catalytic cycle. Catalytic turnover involves the paramagnetic Mo(V) oxidation state, and EPR spectroscopy, especially high-resolution pulsed EPR spectroscopy, provides detailed information about the molecular and electronic structure of the Mo center and the Mo-based sulfite oxidation reaction.
