 590-648 3.12e-18

Uncharacterized polyferredoxin-like protein; This family contains uncharacterized polyferredoxin protein similar to Methanobacterium thermoautotrophicum MvhB. The mvhB is a gene of the methylviologen-reducing hydrogenase operon. It is predicted to contain 12 [4Fe-4S] clusters, and was therefore suggested to be a polyferredoxin. As a subfamily of the beta subunit of the DMSO Reductase (DMSOR) family, it is predicted to function as electron carrier in the reducing reaction.

Uncharacterized polyferredoxin-like protein; This family contains uncharacterized polyferredoxin protein similar to Methanobacterium thermoautotrophicum MvhB. The mvhB is a gene of the methylviologen-reducing hydrogenase operon. It is predicted to contain 12 [4Fe-4S] clusters, and was therefore suggested to be a polyferredoxin. As a subfamily of the beta subunit of the DMSO Reductase (DMSOR) family, it is predicted to function as electron carrier in the reducing reaction.

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.

 590-647 1.11e-08

HycB, HydN and similar proteins; This family includes HycB, the FeS subunit of a membrane-associated formate hydrogenlyase system (FHL-1) in Escherichia coli that breaks down formate, produced during anaerobic fermentation, to H2 and CO2. FHL-1 consists of formate dehydrogenase H (FDH-H) and the hydrogenase 3 complex (Hyd-3). HycB is thought to code for the [4Fe-4S] ferredoxin subunit of hydrogenase 3, which functions as an intermediate electron carrier protein between hydrogenase 3 and formate dehydrogenase. HydN codes for the [4Fe-4S] ferredoxin subunit of FDH-H; a hydN in-frame deletion mutation causes only weak reduction in hydrogenase activity, but loss of more than 60% of FDH-H activity. This pathway is only active at low pH and high formate concentrations, and is thought to provide a detoxification/de-acidification system countering the buildup of formate during fermentation.

 591-656 3.65e-08

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.

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.

 599-647 8.50e-07

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.

 590-647 1.04e-06

glycyl-radical enzyme activating protein; This subset of the radical-SAM family (pfam04055) includes a number of probable activating proteins acting on different enzymes all requiring an amino-acid-centered radical. The closest relatives to this family are the pyruvate-formate lyase activating enzyme (PflA, 1.97.1.4, TIGR02493) and the anaerobic ribonucleotide reductase activating enzyme (TIGR02491). Included within this subfamily are activators of hydroxyphenyl acetate decarboxylase (HdpA), benzylsuccinate synthase (BssD), gycerol dehydratase (DhaB2) as well as enzymes annotated in E. coli as activators of different isozymes of pyruvate-formate lyase (PFLC and PFLE) however, these appear to lack characterization and may activate enzymes with distinctive functions. Most of the sequence-level variability between these forms is concentrated within an N-terminal domain which follows a conserved group of three cysteines and contains a variable pattern of 0 to 8 additional cysteines.

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]

HycB, HydN and similar proteins; This family includes HycB, the FeS subunit of a membrane-associated formate hydrogenlyase system (FHL-1) in Escherichia coli that breaks down formate, produced during anaerobic fermentation, to H2 and CO2. FHL-1 consists of formate dehydrogenase H (FDH-H) and the hydrogenase 3 complex (Hyd-3). HycB is thought to code for the [4Fe-4S] ferredoxin subunit of hydrogenase 3, which functions as an intermediate electron carrier protein between hydrogenase 3 and formate dehydrogenase. HydN codes for the [4Fe-4S] ferredoxin subunit of FDH-H; a hydN in-frame deletion mutation causes only weak reduction in hydrogenase activity, but loss of more than 60% of FDH-H activity. This pathway is only active at low pH and high formate concentrations, and is thought to provide a detoxification/de-acidification system countering the buildup of formate during fermentation.

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.

 599-647 1.42e-04

uncharacterized subfamily of beta subunit of formate dehydrogenase; This subfamily includes the beta-subunit of formate dehydrogenases that are as yet uncharacterized. Members of the DMSO reductase family include formate dehydrogenase N and O (FDH-N, FDH-O) and tungsten-containing formate dehydrogenase (W-FDH) and other similar proteins. FDH-N, a major component of nitrate respiration of Escherichia coli, is involved in the major anaerobic respiratory pathway in the presence of nitrate, catalyzing the oxidation of formate to carbon dioxide at the expense of nitrate reduction to nitrite. It forms a heterotrimer; the alpha-subunit (FDH-G) is the catalytic site of formate oxidation and membrane-associated, incorporating a selenocysteine (SeCys) residue and a [4Fe/4S] cluster in addition to two bis-MGD cofactors, the beta subunit (FDH-H) contains four [4Fe/4S] clusters which transfer the electrons from the alpha subunit to the gamma-subunit (FDH-I), a hydrophobic integral membrane protein, presumably a cytochrome containing two b-type heme groups. W-FDH contains a tungsten instead of molybdenum at the catalytic center. This enzyme seems to be exclusively found in organisms such as hyperthermophilic archaea that live in extreme environments. It is a heterodimer of a large and a small subunit; the large subunit harbors the W site and one [4Fe-4S] center and the small subunit, containing three [4Fe-4S] clusters, functions to transfer electrons.

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]

 581-677 1.11e-03

the FeS subunit of hydrogenase 2; This subfamily includes the beta-subunit of hydrogenase 2 (Hyd-2), an enzyme that catalyzes the reversible oxidation of H2 to protons and electrons. Hyd-2 is membrane-associated and forms an unusual heterotetrameric [NiFe]-hydrogenase in that it lacks the typical cytochrome b membrane anchor subunit that transfers electrons to the quinone pool. The electron transfer subunit of Hyd-2 (HybA) which is predicted to contain four iron-sulfur clusters, is essential for electron transfer from Hyd-2 to menaquinone/demethylmenaquinone (MQ/DMQ) to couple hydrogen oxidation to fumarate reduction.

 591-651 1.12e-03

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.

 591-653 1.17e-03

HycB, HydN and similar proteins; This family includes HycB, the FeS subunit of a membrane-associated formate hydrogenlyase system (FHL-1) in Escherichia coli that breaks down formate, produced during anaerobic fermentation, to H2 and CO2. FHL-1 consists of formate dehydrogenase H (FDH-H) and the hydrogenase 3 complex (Hyd-3). HycB is thought to code for the [4Fe-4S] ferredoxin subunit of hydrogenase 3, which functions as an intermediate electron carrier protein between hydrogenase 3 and formate dehydrogenase. HydN codes for the [4Fe-4S] ferredoxin subunit of FDH-H; a hydN in-frame deletion mutation causes only weak reduction in hydrogenase activity, but loss of more than 60% of FDH-H activity. This pathway is only active at low pH and high formate concentrations, and is thought to provide a detoxification/de-acidification system countering the buildup of formate during fermentation.

 590-651 1.41e-03

uncharacterized subfamily of beta subunit of formate dehydrogenase; This subfamily includes the beta-subunit of formate dehydrogenases that are as yet uncharacterized. Members of the DMSO reductase family include formate dehydrogenase N and O (FDH-N, FDH-O) and tungsten-containing formate dehydrogenase (W-FDH) and other similar proteins. FDH-N, a major component of nitrate respiration of Escherichia coli, is involved in the major anaerobic respiratory pathway in the presence of nitrate, catalyzing the oxidation of formate to carbon dioxide at the expense of nitrate reduction to nitrite. It forms a heterotrimer; the alpha-subunit (FDH-G) is the catalytic site of formate oxidation and membrane-associated, incorporating a selenocysteine (SeCys) residue and a [4Fe/4S] cluster in addition to two bis-MGD cofactors, the beta subunit (FDH-H) contains four [4Fe/4S] clusters which transfer the electrons from the alpha subunit to the gamma-subunit (FDH-I), a hydrophobic integral membrane protein, presumably a cytochrome containing two b-type heme groups. W-FDH contains a tungsten instead of molybdenum at the catalytic center. This enzyme seems to be exclusively found in organisms such as hyperthermophilic archaea that live in extreme environments. It is a heterodimer of a large and a small subunit; the large subunit harbors the W site and one [4Fe-4S] center and the small subunit, containing three [4Fe-4S] clusters, functions to transfer electrons.
