MrpA and MrpD are homologous to NuoL, NuoM and NuoN in complex I over the first 14 transmembrane helices. In this work, the C‐terminal domain of MrpA, outside this conserved area, was investigated. The transmembrane orientation was found to correspond to that of NuoJ in complex I. We have previously demonstrated that the subunit NuoK is homologous to MrpC. The function of the MrpA C‐terminus was tested by expression in a previously used Bacillus subtilis model system. At neutral pH, the… Expand

Differences in the phenotypic effects of mutations in homologous MrpA and MrpD subunits of the multi-subunit Mrp-type Na+/H+ antiporter
The results are consistent with a divergence in adaptations that support the roles of MrpA and MrpD in secondary antiport, as compared to later adaptations supporting homologs in primary proton pumping by the respiratory chain complex I. Expand
Loss of Complex I activity in the Escherichia coli enzyme results from truncating the C-terminus of subunit K, but not from cross-linking it to subunits N or L
Results suggest that while the C-terminus of subunit K has no dynamic role in energy transduction by Complex I, it is vital for the correct assembly of the enzyme. Expand
Functional Role of MrpA in the MrpABCDEFG Na+/H+ Antiporter Complex from the Archaeon Methanosarcina acetivorans
The work is the first reported characterization of an Mrp complex from the domain Archaea, specifically methanogens, for which Mrp is important for acetotrophic growth and bioinformatics analyses indicate that Mrp complexes function in diverse methanogenic pathways. Expand
Painfully Energetic: A tale of two proteins potentially connected
The aim of this work was to better understand the functional relationship between the related protein subunits of complex I, Mrp-antiporter and [NiFe]-hydrogenases and to elucidate the proton translocation pathway in complex I. Expand
Respiratory complex I - Mechanistic insights and advances in structure determination.
Progress in structure determination and functional characterization of complex I are reviewed and current mechanistic models are discussed. Expand
The role of geochemistry and energetics in the evolution of modern respiratory complexes from a proton-reducing ancestor.
It is hypothesized that the diversification of ARC to MBH, MBX, FPO and eventually NUO was driven by the larger energy yields associated with coupling Fd oxidation to the reduction of oxidants with increasing electrochemical potential, including protons, S° and membrane soluble organic compounds such as phenazines and quinone derivatives.

The MrpA, MrpB and MrpD subunits of the Mrp antiporter complex in Bacillus subtilis contain membrane-embedded and essential acidic residues.
This study further investigated the functional involvement of the equivalent conserved acidic residues of other Mrp proteins in heterologous Escherichia coli and natural B. subtilis backgrounds and found them to be conserved in the homologous MrpD/MrpA proteins as well as in thehomologous subunits of H-translocating primary active transporters such as Nuo and Mbh. Expand
Probing the mechanistic role of the long α-helix in subunit L of respiratory Complex I from Escherichia coli by site-directed mutagenesis
Three types of mutations were introduced into the nuoL gene to test the piston‐like function of the NuoL subunit of Complex I, and several substitutions and insertions were made to reduce rigidity of the amphipathic α‐helix, and/or to change its geometry. Expand
Structural Contribution of C-terminal Segments of NuoL (ND5) and NuoM (ND4) Subunits of Complex I from Escherichia coli*
The results suggest an important structural role for the C-terminal segments of both subunits in the NADH-quinone oxidoreductase complex and advocate that the elimination of the last transmembrane helix of NuoM and the TM16 may lead to reduced stability of the membrane arm and therefore of the whole NDH-1 complex. Expand
Homologous protein subunits from Escherichia coli NADH:quinone oxidoreductase can functionally replace MrpA and MrpD in Bacillus subtilis.
The complex I subunits NuoL, NuoM and NuoN are homologous to two proteins, MrpA and MrpD, from one particular class of Na+/H+ antiporters, and demonstrate functional specializations, corroborating that the two proteins have unique specific functions. Expand
Revised transmembrane orientation of the NADH:quinone oxidoreductase subunit NuoA
Novel analyses of NuoA from Escherichia coli complex I expressed as fusion proteins to cytochrome c and to alkaline phosphatase demonstrated that the c‐terminal end of the polypeptide is localized in the bacterial cytoplasm, in contrast to what was previously reported for the homologous NQO7 subunit from Paracoccus denitrificans complex I. Expand
The architecture of respiratory complex I
The architecture of the complex provides strong clues about the coupling mechanism: the conformational changes at the interface of the two main domains may drive the long amphipathic α-helix of NuoL in a piston-like motion, tilting nearby discontinuous TM helices, resulting in proton translocation. Expand
Structure of the membrane domain of respiratory complex I
The structure indicates that proton translocation in Esherichia coli complex I, uniquely, involves coordinated conformational changes in six symmetrical structural elements. Expand
The ‘antiporter module’ of respiratory chain Complex I includes the MrpC/NuoK subunit – a revision of the modular evolution scheme
It is shown that MrpC and NuoK are homologous proteins, and it is concluded that the last common ancestor of the Complex I enzyme family and membrane bound NiFe hydrogenases of type 3 and 4 contained the N LuoKLMN subunit module. Expand
Structure of the Hydrophilic Domain of Respiratory Complex I from Thermus thermophilus
The crystal structure of the hydrophilic domain (peripheral arm) of complex I from Thermus thermophilus has been solved at 3.3 angstrom resolution and reveals new aspects of the mechanism and evolution of the enzyme. Expand
Crystal structure of the entire respiratory complex I
The structure suggests that a unique, out-of-the-membrane quinone-reaction chamber enables the redox energy to drive concerted long-range conformational changes in the four antiporter-like domains, resulting in translocation of four protons per cycle. Expand
