Tetrameric architecture of an active phenol-bound form of the AAA+ transcriptional regulator DmpR

Abstract

DmpR is a bacterial enhancer binding protein from the AAA+ family of ATPases that binds aromatic compounds and controls the transcription of genes involved in the degradation of toxic pollutants. Here, the authors present the crystal structure of phenol-bound DmpR, which forms a tetramer and discuss its signal transduction mechanism.
