Figure 2From: Cysteine coordination of Pb(II) is involved in the PbrR-dependent activation of the lead-resistance promoter, PpbrA, from Cupriavidus metallidurans CH34Alignment of selected promoters for structural genes regulated by MerR family metal responsive regulators: PbrR[4]; MerR[10], ZntR[23], CueR[20]. The −35 and −10 sequences are marked in BOLD. Arrows show dyad symmetrical DNA sequences within the promoters.Back to article page
