+ | The transcriptional regulator DntR, a member of the LysR family, is a central element in a prototype bacterial cell-based biosensor for the detection of hazardous contamination of soil and groundwater by dinitrotoluenes. To optimise the sensitivity of the biosensor for such compounds we have chosen a rational design of the inducer-binding cavity based on knowledge of the three-dimensional structure of DntR. We report two crystal structures of DntR with acetate (resolution 2.6 angstroms) and thiocyanate (resolution 2.3 angstroms), respectively, occupying the inducer-binding cavity. These structures allow for the construction of models of DntR in complex with salicylate (Kd approximately or = 4 microM) and 2,4-dinitrotoluene that provide a basis for the design of mutant DntR with enhanced specificity for dinitrotoluenes. In both crystal structures DntR crystallises as a homodimer with a "head-to-tail" arrangement of monomers in the asymmetric unit. Analysis of the crystal structure has allowed the building of a full-length model of DntR in its biologically active homotetrameric form consisting of two "head-to-head" dimers. The implications of this model for the mechanism of transcription regulation by LysR proteins are discussed. | ||
