The promoters of ymcA and ylbF are regulated by Spo0A. The following strains were grown in DSM, and samples were taken at the indicated time points: PymcA-lacZ+ (BD6413), PylbF-lacZ+ (BD6414), PyaaT-lacZ+ (BD5635), PymcA-lacZ+ spo0A (BD6530), PylbF-lacZ+ spo0A (BD6531) and PyaaT-lacZ+ spo0A (BD6532). β-galactosidase activities were determined as described in Experimental procedures. Bars represent an average of 3–4 independent experiments, and error bars represent standard deviations. All strains were grown in the presence of 1 mM IPTG.
