Abstract
Oxidation of reduced inorganic sulfur compounds by bacteria is a major component of the biogeochemical sulfur cycle. Our understanding of this metabolic process at the molecular level is, however, rudimentary. Using the photosynthetic 'sulfur-oxidising' bacterium Rhodovulum sulfidophilum (formerly Rhodobacter sulfidophilus) as our model system we will identify the gene products required for the oxidation of thiosulfate and sulfide to sulfate. This research will provide the basis for biochemical and physiological studies of the sulfur oxidation pathways as well as structural, spectroscopic and enzymological analysis of the proteins involved. The research will have relevance for inorganic sulfur metabolism in non-photosynthetic as well as photosynthetic bacteria.
