TABLE 1.

Effect of CRP and cAMP on transcription from the major IS2 promoter

Bacterial strain	Luciferase activity (RLU)a	Relative fold increaseb
TP7811 (WT)c	(2.7 ± 0.5) × 105	1.0
TP7839 (Δcrp)	(10.8 ± 0.6) × 105	4.0
TP7860 (Δcya)	(46.3 ± 3.0) × 105	17.1

^aEach value represents the mean of four independent assays ± standard deviation. 

^bFold increase in RLU is relative to that of TP7811(pACPIS2-Lux), which is set as 1. 

^cWT, wild type.
