What's a GeneRIF?
  1. To explore the functional relevance of the pseudosymmetric inverted-repeat structures of the antiporter-like subunits NuoL/M/N, we constructed a symmetry-related structure of a possible alternate-access state.

    Title: Mutagenesis of the L, M, and N subunits of Complex I from Escherichia coli indicates a common role in function.
  3. Data show that in L, M, and N subunits of Complex I, transmembrane helices 9 and 12 are predicted to form the discontinuous helices, which are likely to play a key role in function.

  4. Data show that none of the mutants showed alteration in the detectable levels of expressed NuoM or on the NDH-1 assembly.
