Oxidation of Reduced Inorganic Sulfur Compounds by Bacteria: Emergence of a Common Mechanism?
Biological oxidation of hydrogen sulfide to sulfate is one of the major reactions of the global sulfur cycle. Reduced inorganic sulfur compounds (referred to below as sulfur) are exclusively oxidizedExpand
Prokaryotic sulfur oxidation.
Recent biochemical and genomic data differentiate the sulfur oxidation pathway of Archaea from those of Bacteria. From these data it is evident that members of the Alphaproteobacteria harbor theExpand
Novel genes coding for lithotrophic sulfur oxidation of Paracoccus pantotrophus GB17.
The gene region coding for lithotrophic sulfur oxidation of Paracoccus pantotrophus GB17 is located on a 13-kb insert of plasmid pEG12. Upstream of the previously described six open reading framesExpand
The cysteine residue of the SoxY protein as the active site of protein‐bound sulfur oxidation of Paracoccus pantotrophus GB17
Four proteins of Paracoccus pantotrophus are required for hydrogen sulfide‐, sulfur‐, thiosulfate‐ and sulfite‐dependent horse heart cytochrome c reduction. The lack of free intermediates suggested aExpand
Tracing dung-derived carbon in temperate grassland using 13C natural abundance measurements.
Abstract To understand the role of dung-derived carbon in the carbon cycle of grazed temperate grasslands, we need a procedure to trace dung-derived C. The natural 13 C tracer technique of applyingExpand

Reduced inorganic sulfur compounds are oxidized by members of the domains Archaea and Bacteria. These compounds are used as electron donors for anaerobic phototrophic and aerobic chemotrophic growth,Expand
Novel genes of the sox gene cluster, mutagenesis of the flavoprotein SoxF, and evidence for a general sulfur-oxidizing system in Paracoccus pantotrophus GB17.
The novel genes soxFGH were identified, completing the sox gene cluster of Paracoccus pantotrophus coding for enzymes involved in lithotrophic sulfur oxidation. The periplasmic SoxF, SoxG, and SoxHExpand

Sulfur oxidation in Paracoccus pantotrophus: interaction of the sulfur-binding protein SoxYZ with the dimanganese SoxB protein.
The central protein of the sulfur-oxidizing enzyme system of Paracoccus pantotrophus, SoxYZ, formed complexes with subunits associated and covalently bound. In denaturing SDS-polyacrylamide gelExpand
Evidence for two pathways of thiosulfate oxidation in Starkeya novella (formerly Thiobacillus novellus)
Abstract. The pathway of thiosulfate oxidation in the facultatively chemolithotrophic, sulfur-oxidizing bacterium Starkeya novella (formerly Thiobacillus novellus) has not been established beyondExpand
