TCS tuning an E. coli aspartate sensor. a The Taz-OmpR aspartate sensing TCS in E. coli. The Taz SK is composed of the Tar sensing domain fused to the EnvZ DhP and CA domains. Taz signals to OmpR which controls transcription from the P ompF output promoter. b The relationship between the phosphatase activity of the mutant as measured by Inouye and colleagues36 and the K1/2 fit parameter from transfer function fits in Supplementary Fig. 5. Error bars are the 95% confidence interval of the K1/2 fit parameter
