Fig 1. Effect of nhaR mutation on csrA gene expression.

Growth curves (dashed lines) and activity of csrA’-’lacA fusion (solid lines) in WT and nhaR mutant of E. coli MG1655 grown at 26C in LB pH8.4 TAPS (A). Western blot analysis of CsrA protein in WT and nhaR mutant (B). RpoB was used as loading control. Data shows representative results from 4 experiments.
