Activation of genes involved in AMP resistance by arcA. Plasmid pGEM-T or pGEM-T-arcA was introduced into strains containing a dltB-uidA, dltD-uidA, phoS-lacZ, or arnB-uidA transcriptional fusion. The ratios of expression in strains with pGEM-T-arcA versus those in strains with pGEM-T are shown. Values represent the means ± SDs from at least four separate experiments.
