Figure 4From: Cysteine coordination of Pb(II) is involved in the PbrR-dependent activation of the lead-resistance promoter, PpbrA, from Cupriavidus metallidurans CH34 β-galactosidase assays in C. metallidurans AE104 of P pbrA activation in response to 20 μM Pb(II) on wild-type PbrR and its cysteine mutants in pMUPbrR/P pbrA.
