KinB acts as a phosphatase to regulate P. aeruginosa acute virulence. (A) Pyocyanin produced by different P. aeruginosa strains after 22 h of growth at 37°C and 250 rpm. Error bars indicate standard errors of the means computed from three technical replicates. The data are representative of two biological replicates. (B) Elastase activities from culture fluids from 21-h cultures in LB medium measured in elastin-Congo red assays. The A₄₉₅ for each strain is shown as a percentage of the mean wild-type absorbance. Error bars indicate standard errors of the means computed from three technical replicates. The data are representative of two biological replicates.
