Fig. 5.

Transcriptional analysis of the pilF promoter (PpilF) region in an N. gonorrhoeae MS11-A background. The arrows are the terminal CR. An X indicates a particular promoter that was mutated. The amount of CAT protein produced by each N. gonorrhoeae reporter strain was quantified by CAT ELISAs, and at least 3 independent biological samples were prepared. The CAT level is expressed as the percentage of the wild-type level produced by JKD5245. The error bars represent standard deviations of the mean.
