Location of the norA promoter mutations found in norA overexpressing strains following antimicrobial exposure. The nucleotides are numbered taking into consideration the norA starting codon. MgrA binding sites are identified by black lines. The consensus motifs −35 and −10 are also identified in black lines. The symbol * identifies the nucleotide −132 (A) which is absent in SM2 and SM50 norA promoter sequence. The sites of IS256 insertion within the norA promoter region of strain SM2 exposed to CET or EtBr MIC are also indicated (dotted arrows)
