photosystem I iron-sulfur protein PsaC; Members of this family are PsaC, an essential component of photosystem I (PS-I) reaction center in Cyanobacteria and chloroplasts. This small protein, about 80 amino acids in length, contains two copies of the ferredoxin-like 4Fe-4S binding site (pfam00037) and therefore eight conserved Cys residues. This protein is also called photosystem I subunit VII. [Energy metabolism, Photosynthesis]

 9-71 2.71e-08

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.

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.

 5-67 4.63e-05

D subunit of Archaeal RNA polymerase; The D subunit of archaeal RNA polymerase (RNAP) is involved in the assembly of RNAP subunits. RNAP is a large multi-subunit complex responsible for the synthesis of RNA. It is the principal enzyme of the transcription process, and is a final target in many regulatory pathways that control gene expression in all living cells. A single distinct RNAP complex is found in archaea, which may be responsible for the synthesis of all RNAs. The archaeal RNAP harbors homologues of all eukaryotic RNAP II subunits with two exceptions (RPB8 and RPB9). The 12 archaeal subunits are designated by letters and can be divided into three functional groups that are engaged in: (I) catalysis (A'/A", B'/B" or B); (II) assembly (L, N, D and P); and (III) auxiliary functions (F, E, H and K). The D subunit is equivalent to the RPB3 subunit of eukaryotic RNAP II. It contains two subdomains: one subdomain is similar the eukaryotic Rpb11/AC19/archaeal L subunit which is involved in dimerization, and the other is an inserted beta sheet subdomain. The assembly of the two largest archaeal RNAP subunits that provide most of the enzyme's catalytic functions depends on the presence of the archaeal D/L heterodimer.

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.

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]

 10-81 5.74e-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.

beta subunit of formate dehydrogenase O (FDH-O) and similar proteins; This subfamily includes beta subunit of formate dehydrogenase family O (FDH-O), which is highly homologous to formate dehydrogenase N (FDH-N), a member of the DMSO reductase family. In E. coli three formate dehydrogenases are synthesized that are capable of oxidizing formate; Fdh-H, couples formate disproportionation to hydrogen and CO2, and is part of the cytoplasmically oriented formate hydrogenlyase complex, while FDH-N and FDH-O indicate their respective induction after growth with nitrate and oxygen. Little is known about FDH-O, although it shows formate oxidase activity during aerobic growth and is also synthesized during nitrate respiration, similar to FDH-N.

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.
