Figure 4From: Bacillus cereus Fnr binds a [4Fe-4S] cluster and forms a ternary complex with ResD and PlcRBinding of apo- and holoFnr to promoter regions of fnr , hbl and nhe genes determined by EMSA. DNA probes corresponding to fnr (A), nhe (B), hbl1 (C), hbl2 (D) and a negative control (E) were bound with increasing concentrations of apoFnr (−) and holoFnr (+) as indicated. The results are representative of triplicate experiments.Back to article page
