>gnl|CDD|48613 cd03064, TRX_Fd_NuoE, 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..
