 77-154 2.55e-32

TRX-like [2Fe-2S] Ferredoxin (Fd) family, NADH:ubiquinone oxidoreductase (Nuo) subunit E subfamily; Nuo, also called respiratory chain Complex 1, is the entry point for electrons into the respiratory chains of bacteria and the mitochondria of eukaryotes. It is a multisubunit complex with at least 14 core subunits. It catalyzes the electron transfer of NADH to quinone coupled with the transfer of protons across the membrane, providing the proton motive force required for energy-consuming processes. Electrons are transferred from NADH to quinone through a chain of iron-sulfur clusters in Nuo, including the [2Fe-2S] cluster present in NuoE core subunit, also called the 24 kD subunit of Complex 1. This subfamily also include formate dehydrogenases, NiFe hydrogenases and NAD-reducing hydrogenases, that contain a NuoE domain. A subset of these proteins contain both NuoE and NuoF in a single chain. NuoF, also called the 51 kD subunit of Complex 1, contains one [4Fe-4S] cluster and also binds the NADH substrate and FMN.

Thioredoxin (TRX)-like [2Fe-2S] Ferredoxin (Fd) family; composed of [2Fe-2S] Fds with a TRX fold (TRX-like Fds) and proteins containing domains similar to TRX-like Fd including formate dehydrogenases, NAD-reducing hydrogenases and the subunit E of NADH:ubiquinone oxidoreductase (NuoE). TRX-like Fds are soluble low-potential electron carriers containing a single [2Fe-2S] cluster. The exact role of TRX-like Fd is still unclear. It has been suggested that it may be involved in nitrogen fixation. Its homologous domains in large redox enzymes (such as Nuo and hydrogenases) function as electron carriers.

TRX-like [2Fe-2S] Ferredoxin (Fd) family, NADH:ubiquinone oxidoreductase (Nuo) subunit E subfamily, NAD-dependent formate dehydrogenase (FDH) gamma subunit; composed of proteins similar to the gamma subunit of NAD-linked FDH of Ralstonia eutropha, a soluble enzyme that catalyzes the irreversible oxidation of formate to carbon dioxide accompanied by the reduction of NAD+ to NADH. FDH is a heteromeric enzyme composed of four nonidentical subunits (alpha, beta, gamma and delta). The FDH gamma subunit is closely related to NuoE, which is part of a multisubunit complex (Nuo) catalyzing the electron transfer of NADH to quinone coupled with the transfer of protons across the membrane. Electrons are transferred from NADH to quinone through a chain of iron-sulfur clusters in Nuo, including the [2Fe-2S] cluster present in NuoE. Similarly, the FDH gamma subunit is hypothesized to be involved in an electron transport chain involving other FDH subunits, upon the oxidation of formate.

 89-154 9.44e-13

TRX-like [2Fe-2S] Ferredoxin (Fd) family, NADH:ubiquinone oxidoreductase (Nuo) subunit E subfamily, hoxF; composed of proteins similar to the NAD-reducing hydrogenase (hoxS) alpha subunit of Alcaligenes eutrophus H16. HoxS is a cytoplasmic hydrogenase catalyzing the oxidation of molecular hydrogen accompanied by the reduction of NAD. It is composed of four structural subunits encoded by the genes hoxF, hoxU, hoxY and hoxH. The hoxF protein (or alpha subunit) is a fusion protein containing an N-terminal NuoE-like domain and a C-terminal NuoF domain. NuoE and NuoF are components of Nuo, a multisubunit complex catalyzing the electron transfer of NADH to quinone coupled with the transfer of protons across the membrane. Electrons are transferred from NADH to quinone through a chain of iron-sulfur clusters in Nuo, including the [2Fe-2S] cluster in NuoE and the [4Fe-4S] cluster in NuoF. In addition, NuoF is also the NADH- and FMN-binding subunit. HoxF may be involved in the electron transport chain during the NAD-dependent oxidation of hydrogen through its NuoF domain. The NuoE-like domain of hoxF contains only one conserved cysteine in its putative active site, compared to four cysteines in NuoE, and may have lost the ability to bind [2Fe-2S] clusters.

TRX-like [2Fe-2S] Ferredoxin (Fd) family, NADH:ubiquinone oxidoreductase (Nuo) subunit E family, Tungsten-containing formate dehydrogenase (W-FDH) beta subunit; composed of proteins similar to the W-FDH beta subunit of Methylobacterium extorquens. W-FDH is a heterodimeric NAD-dependent enzyme catalyzing the conversion of formate to carbon dioxide. The beta subunit is a fusion protein containing an N-terminal NuoE domain and a C-terminal NuoF domain. NuoE and NuoF are components of Nuo, a multisubunit complex catalyzing the electron transfer of NADH to quinone coupled with the transfer of protons across the membrane.
