  Subject Areas on Research

  • Mechanism of corepressor-mediated specific DNA binding by the purine repressor. 
  • Plasmid protein TubR uses a distinct mode of HTH-DNA binding and recruits the prokaryotic tubulin homolog TubZ to effect DNA partition. 
  • Prokaryotic transcription regulators: more than just the helix-turn-helix motif. 
  • Relaxed constraint and evolutionary rate variation between basic helix-loop-helix floral anthocyanin regulators in Ipomoea. 
  • Structural basis for ADP-mediated transcriptional regulation by P1 and P7 ParA. 
  • Structural basis for cooperative DNA binding by two dimers of the multidrug-binding protein QacR. 
  • Structural comparison of the free and DNA-bound forms of the purine repressor DNA-binding domain.
