cytochrome c oxidase accessory protein FixG; Member of this ferredoxin-like protein family are found exclusively in species with an operon encoding the cbb3 type of cytochrome c oxidase (cco-cbb3), and near the cco-cbb3 operon in about half the cases. The cco-cbb3 is found in a variety of proteobacteria and almost nowhere else, and is associated with oxygen use under microaerobic conditions. Some (but not all) of these proteobacteria are also nitrogen-fixing, hence the gene symbol fixG. FixG was shown essential for functional cco-cbb3 expression in Bradyrhizobium japonicum. : Pssm-ID: 274278 [Multi-domain] Cd Length: 434 Bit Score: 633.19 E-value: 0e+00

The periplasmic nitrate reductase NapABC of Escherichia coli likely functions during anaerobic growth in low-nitrate environments; napF operon expression is activated by cyclic AMP receptor protein (Crp). NapF is a subfamily of the beta subunit of DMSO reductase (DMSOR) family. DMSOR family members have a large, periplasmic molybdenum-containing alpha subunit as well as a small beta FeS subunit, and may also have a small gamma subunit. The beta subunit contains four Fe4/S4 and/or Fe3/S4 clusters which transfer the electrons from the alpha subunit to a hydrophobic integral membrane protein, presumably a cytochrome containing two b-type heme groups. The reducing equivalents are then transferred to menaquinone, which finally reduces the electron-accepting enzyme system.

polysulfide reductase beta (PsrB) subunit; This family includes the beta subunit of bacterial polysulfide reductase (PsrABC), an integral membrane-bound enzyme responsible for quinone-coupled reduction of polysulfides, a process important in extreme environments such as deep-sea vents and hot springs. Polysulfide reductase contains three subunits: a catalytic subunit PsrA, an electron transfer PsrB subunit and the hydrophobic transmembrane PsrC subunit. PsrB belongs to the DMSO reductase superfamily that contains [4Fe-4S] clusters which transfer the electrons from the A subunit to the hydrophobic integral membrane C subunit via the B subunit. In Shewanella oneidensis, which has highly diverse anaerobic respiratory pathways, PsrABC is responsible for H2S generation as well as its regulation via respiration of sulfur species. PsrB transfers electrons from PsrC (serving as quinol oxidase) to the catalytic subunit PsrA for reduction of corresponding electron acceptors. It has been shown that T. thermophilus polysulfide reductase could be a key energy-conserving enzyme of the respiratory chain, using polysulfide as the terminal electron acceptor and pumping protons across the membrane.

uncharacterized subfamily of DMSO Reductase beta subunit family; This family consists of the small beta iron-sulfur (FeS) subunit of the DMSO Reductase (DMSOR) family. Members of this family also contain a large, periplasmic molybdenum-containing alpha subunit and may have a small gamma subunit as well. Examples of heterodimeric members with alpha and beta subunits include arsenite oxidase, and tungsten-containing formate dehydrogenase (FDH-T) while heterotrimeric members containing alpha, beta, and gamma subunits include formate dehydrogenase-N (FDH-N), and nitrate reductase (NarGHI). The beta subunit contains four Fe4/S4 and/or Fe3/S4 clusters which transfer the electrons from the alpha subunit to a hydrophobic integral membrane protein, presumably a cytochrome containing two b-type heme groups. The reducing equivalents are then transferred to menaquinone, which finally reduces the electron-accepting enzyme system.

electron transport complex, RnfABCDGE type, B subunit; The six subunit complex RnfABCDGE in Rhodobacter capsulatus encodes an apparent NADH oxidoreductase responsible for electron transport to nitrogenase, necessary for nitrogen fixation. A closely related complex in E. coli, RsxABCDGE (Reducer of SoxR), reduces the 2Fe-2S-containing superoxide sensor SoxR, active as a transcription factor when oxidized. This family of putative NADH oxidoreductase complexes exists in many of the same species as the related NQR, a Na(+)-translocating NADH-quinone reductase, but is distinct. This model describes the B subunit. [Energy metabolism, Electron transport] Pssm-ID: 273887 [Multi-domain] Cd Length: 165 Bit Score: 39.78 E-value: 1.11e-03

beta FeS subunits of formate dehydrogenase N (FDH-N) and similar proteins; This family contains beta FeS subunits of several dehydrogenases in the DMSO reductase superfamily, including formate dehydrogenase N (FDH-N), tungsten-containing formate dehydrogenase (W-FDH) and other similar proteins. FDH-N is a major component of nitrate respiration of Escherichia coli; it catalyzes the oxidation of formate to carbon dioxide, donating the electrons to a second substrate to a cytochrome. W-FDH contains a tungsten instead of molybdenum at the catalytic center and seems to be exclusively found in organisms such as hyperthermophilic archaea that live in extreme environments. It catalyzes the oxidation of formate to carbon dioxide, donating the electrons to a second substrate. Pssm-ID: 319888 [Multi-domain] Cd Length: 156 Bit Score: 39.31 E-value: 1.56e-03
