Comparing the salicylate-binding sites of E. coli and M. thermoautotrophicum MarRs with those of NMB1585. (a) Ribbon diagram showing the NMB1585 dimer with the relative salicylate-binding sites in E. coli (PDB code 1jgs
; SalA and SalB) and M. thermoautotrophicum (PDB code 3bpv
; Sal1 and Sal2) marked by salicylate molecules drawn as space-filling objects; (b) and (c) comparison of the M. thermoautotrophicum MarR salicylate-binding sites with the corresponding regions of NMB1585 by overlapping the two chains separately; the backbones are shown as ribbons and the side chains as sticks, with M. thermoautotrophicum MarR coloured grey and orange and NMB1585 in blue and cyan; the salicylate molecules are shown as thicker sticks and coloured yellow. |
