SULFITE DEHYDROGENASE FROM STARKEYA NOVELLA
Overview
Sulfite-oxidizing molybdoenzymes convert the highly reactive and therefore, toxic sulfite to sulfate and have been identified in insects, animals, plants, and bacteria. Although the well studied enzymes from higher, animals serve to detoxify sulfite that arises from the catabolism of, sulfur-containing amino acids, the bacterial enzymes have a central role, in converting sulfite formed during dissimilatory oxidation of reduced, sulfur compounds. Here we describe the structure of the Starkeya novella, sulfite dehydrogenase, a heterodimeric complex of the catalytic, molybdopterin subunit and a c-type cytochrome subunit, that reveals the, molecular mechanism of intramolecular electron transfer in, sulfite-oxidizing enzymes. The close approach of the two redox centers in, the protein complex ... [(full description)]
