FIG. 6.

Mutation of the dipeptide permease transporter causes greater sensitivity to CORM-3. Cultures of WT and dppB were grown in the Evans medium to early-exponential phase before washing and dilution in PBS to ∼10⁶ colony forming units (CFU)·ml⁻¹. Cells were exposed to 0.5 μM CORM-3 and incubated for a further hour before plating serial dilutions to determine the viability as a percentage survival compared to no-CORM-3 treatment. N=3±SEM, * denotes p-value<0.01 as determined by the Student's t-test. CFU, colony forming units.
