Effect of changes around the putative Ers box on expression from the ace promoter. When grown in the presence of serum, β-galactosidase activities of P435 and its derivatives were determined. Sequence information of fusion plasmids is indicated in the box. The putative Ers binding site (AACAAATGTTA) is underlined. Deletion constructs are indicated above the sequence whereas substitution constructs are indicated below the sequence. P176, indicated with the arrow, extends from the Ers box to 27 bp inside the ace gene. Bars with standard error indicate the means of the duplicate/triplicate assay using strains collected at early exponential phase. Strains were grown in BHI (white bar) or BHIS (gray bar).
