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
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
The unusal redox centers of SoxXA, a novel c-type heme-enzyme essential for chemotrophic sulfur-oxidation of Paracoccus pantotrophus.
The heterodimeric hemoprotein SoxXA, essential for lithotrophic sulfur oxidation of the aerobic bacterium Paracoccus pantotrophus, was examined by a combination of spectroelectrochemistry and EPRExpand
Structure of the cytochrome complex SoxXA of Paracoccus pantotrophus, a heme enzyme initiating chemotrophic sulfur oxidation.
The sulfur-oxidizing enzyme system (Sox) of the chemotroph Paracoccus pantotrophus is composed of several proteins, which together oxidize hydrogen sulfide, sulfur, thiosulfate or sulfite andExpand
SoxRS-mediated regulation of chemotrophic sulfur oxidation in Paracoccus pantotrophus.
Paracoccus pantotrophus GB17 requires thiosulfate for induction of the sulfur-oxidizing (Sox) enzyme system. The soxRS genes are divergently oriented to the soxVWXYZA-H genes. soxR predicts aExpand
Regulation of the operon responsible for broad-spectrum mercury resistance inStreptomyces lividans 1326
The broad-spectrum mercury resistance ofStreptomyces lividans 1326 is mediated by six open reading frames (orf). These are arranged in two divergently transcribed operons. Theorfs merA (mercuricExpand
Purification and characterization of MerR, the regulator of the broad-spectrum mercury resistance genes in Streptomyces lividans 1326
Streptomyces lividans 1326 carries inducible mercury resistance genes on the chromosome, which are arranged in two divergently transcribed operons. Expression of the genes is negatively regulated byExpand
