From: ComCED signal loop precisely regulates nlmC expression in Streptococcus mutans
Effect of exogenous CSP on nlmC and nlmAB expression. Expression of nlmC and nlmAB is detected by beta-galactosidase activity in the cassette of promoter–lacZ which is integrated in the genome of WT/pA-LacZ or WT/pC-LacZ. Dashed line: liquid medium without exogenous CSP. Solid line: liquid medium supplying with 0.8 μg/mL CSP. Square symbols (■, □): WT/pA-LacZ. Triangle symbols (▲, △): WT/pC-LacZ
