FIGURE 3.

The importance of the localization of MepM and MepS on their function. (A) The wild-type, mepM mutant, and mepM mutant cells harboring the indicated plasmids were serially diluted from 10⁸ to 10⁴ cells/mL in 10-fold steps and spotted onto an LB plate or LB plates containing 750 mM NaCl and the indicated concentrations of arabinose. (B) The wild-type, mepS mutant, and mepS mutant cells harboring the indicated plasmids were serially diluted from 10⁸ to 10⁴ cells/mL in 10-fold steps and spotted onto an LB plate or LB plates containing 1 mM EDTA and the indicated concentrations of arabinose.
