Transcriptional analysis of the pilG promoter (PpilG) region in an N. gonorrhoeae MS11-A background. The arrows are the terminal CR. The X indicates the mutation of a putative −10 box termed P1. 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 strain JKD5243. The error bars represent standard deviations of the mean.
