Figure 10. Effect of PAβN on nitrocefin hydrolysis by intact cells of wild-type E. coli MG1655 and its tolC deletion mutant.

Figure 10

Both strains were transformed with pMMB67HE before use. Exponentially growing cells in LB containing 100 µg/ml of AMP were harvested and resuspended in fresh LB for the assay. Nitrocefin hydrolysis was monitored by OD486 nm in a 384-well plate with a plate reader after exposure to PAβN for 10 min. (A) shows results from Wild-type/pV, and (B) shows results from ΔC/pV.
