Representative growth curves of mutants <i>Stop</i>OE1472F, <i>Ins</i>OE1475F and ΔOE1477R in synthetic medium supplemented with either 1.1 mM DHQ (A, C and E) or 1.1 mM Shikimate (B, D and F).

<p>WT (<b>▪</b>) and mutant cells (<b>□</b>) were grown as described for Fig. 6. Gn times shown above the lines are for WT cells, and Gn times below the lines are for mutants. The growth of mutant ΔOE1477R in synthetic medium supplemented with DHQ was linear.(<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0107475#pone-0107475-g007" target="_blank">Fig.7F</a>).
