What's a GeneRIF?
  1. AcrBA-TolC complex becomes unstable upon the induction of AcrD, which presumably replaces AcrB in the ternary complex. Such instability is suppressed upon the addition of AcrB-specific substrates. The assembly of resistance-nodulation-cell division-type efflux system is a regulated dynamic process that provides bacteria with a highly flexible repertoire of survival strategies to cope with a wide spectrum of antibiotics.
    Title: Substrate-dependent dynamics of the multidrug efflux transporter AcrB of Escherichia coli.
  2. multiple deletion of acrB, acrD, and mdtABC resulted in a significant decrease in enterobactin export and that plasmids carrying the acrAB, acrD, or mdtABC genes restored the decrease in enterobactin export exhibited by the DeltaacrB acrD mdtABC mutant.
    Title: AcrB, AcrD, and MdtABC multidrug efflux systems are involved in enterobactin export in Escherichia coli.
  3. AcrD can also capture aminoglycosides from the periplasm to extrude them into the medium in intact cells, acting as a "periplasmic vacuum cleaner."
    Title: Aminoglycosides are captured from both periplasm and cytoplasm by the AcrD multidrug efflux transporter of Escherichia coli.
