Thiamine pyrophosphate (TPP family), PFOR_PNO subfamily, TPP-binding module; composed of proteins similar to the single subunit pyruvate ferredoxin oxidoreductase (PFOR) of Desulfovibrio Africanus, present in bacteria and amitochondriate eukaryotes. This subfamily also includes proteins characterized as pyruvate NADP+ oxidoreductase (PNO). These enzymes are dependent on TPP and a divalent metal cation as cofactors. PFOR and PNO catalyze the oxidative decarboxylation of pyruvate to form acetyl-CoA, a crucial step in many metabolic pathways. Archaea, anaerobic bacteria and eukaryotes that lack mitochondria (and therefore pyruvate dehydrogenase) use PFOR to oxidatively decarboxylate pyruvate, with ferredoxin or flavodoxin as the electron acceptor. The PFOR from cyanobacterium Anabaena (NifJ) is required for the transfer of electrons from pyruvate to flavodoxin, which reduces nitrogenase.

The PYR domain is found in many key metabolic enzymes which use TPP (also known as thiamine diphosphate) as a cofactor. TPP binds in the cleft formed by a PYR domain and a PP domain. The PYR domain, binds the aminopyrimidine ring of TPP, the PP domain binds the diphosphate residue. A polar interaction between the conserved glutamate of the PYR domain and the N1' of the TPP aminopyrimidine ring is shared by most TPP-dependent enzymes, and participates in the activation of TPP. The PYR and PP domains have a common fold, but do not share strong sequence conservation. The PP domain is not included in this sub-family. Most TPP-dependent enzymes have the PYR and PP domains on the same subunit although these domains can be alternatively arranged in the primary structure. TPP-dependent enzymes are multisubunit proteins, the smallest catalytic unit being a dimer-of-active sites. For many of these enzymes the active sites lie between PP and PYR domains on different subunits. However, for the homodimeric enzyme Desulfovibrio africanus pyruvate:ferredoxin oxidoreductase (PFOR), each active site lies at the interface of the PYR and PP domains from the same subunit. This subfamily includes proteins characterized as pyruvate NADP+ oxidoreductase (PNO). PFOR and PNO catalyze the oxidative decarboxylation of pyruvate to form acetyl-CoA, a crucial step in many metabolic pathways. The facultative anaerobic mitochondrion of the photosynthetic protist Euglena gracilis oxidizes pyruvate with PNO. IOR catalyzes the oxidative decarboxylation of arylpyruvates, such as indolepyruvate or phenylpyruvate. Pssm-ID: 132917 [Multi-domain] Cd Length: 160 Bit Score: 170.37 E-value: 1.16e-48

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.

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.

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.

707-772 | 2.96e-03 | ||||||||||||||||
uncharacterized beta subfamily of DMSO Reductase similar to Desulfonauticus sp PhsB; This family includes beta FeS subunits of anaerobic DMSO reductase (DMSOR) superfamily that have yet to be characterized. DMSOR consists of a large, periplasmic molybdenum-containing alpha subunit as well as a small beta FeS subunit, and may also have a small gamma subunit. Examples of heterodimeric members with alpha and beta subunits include arsenite oxidase, and the tungsten-containing formate dehydrogenase (FDH-T). Examples of 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.

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.
