 62-139 7.82e-13

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.

NADH-quinone oxidoreductase, chain I; This model represents the I subunit (one of 14: A->N) of the NADH-quinone oxidoreductase complex I which generally couples NADH and ubiquinone oxidation/reduction in bacteria and mammalian mitochondria, but may act on NADPH and/or plastoquinone in cyanobacteria and plant chloroplasts. This model excludes "I" subunits from the closely related F420H2 dehydrogenase and formate hydrogenlyase complexes. [Energy metabolism, Electron transport]

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 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.

 55-119 9.28e-07

Beta subunit of the DMSO Reductase (DMSOR) 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.

The beta FeS subunit of formate dehydrogenase-N (FDH-N); This subfamily contains beta FeS subunit of formate dehydrogenase-N (FDH-N), a member of the DMSO reductase family. FDH-N 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. Thus, FDH-N is a major component of nitrate respiration of Escherichia coli. This integral membrane enzyme 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.

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]

 60-158 2.46e-05

Acetyl-CoA synthase (ACS), also known as acetyl-CoA decarbonylase, is found in acetogenic and methanogenic organisms and is responsible for the synthesis and breakdown of acetyl-CoA. ACS forms a heterotetramer with carbon monoxide dehydrogenase (CODH) consisting of two ACS and two CODH subunits. CODH reduces carbon dioxide to carbon monoxide and ACS then synthesizes acetyl-CoA from carbon monoxide, CoA, and a methyl group donated by another protein (CoFeSP). ACS has three structural domains, an N-terminal rossman fold domain with a helical region at its N-terminus which interacts with CODH, and two alpha + beta fold domains. A Ni-Fe-S center referred to as the A-cluster is located in the C-terminal domain. A large cavity exists between the three domains which may bind CoA.

 55-116 4.89e-04

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.

 55-121 5.11e-04

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.

succinate dehydrogenase and fumarate reductase iron-sulfur protein; Succinate dehydrogenase and fumarate reductase are reverse directions of the same enzymatic interconversion, succinate + FAD+ = fumarate + FADH2 (EC 1.3.11.1). In E. coli, the forward and reverse reactions are catalyzed by distinct complexes: fumarate reductase operates under anaerobic conditions and succinate dehydrogenase operates under aerobic conditions. This model also describes a region of the B subunit of a cytosolic archaeal fumarate reductase. [Energy metabolism, Aerobic, Energy metabolism, Anaerobic, Energy metabolism, TCA cycle]

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.

 63-120 5.68e-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.

 55-119 6.73e-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.
