Amount of biofilms formed as measured by crystal violet staining for (A) Strains ssrAH1, ssrAD, ssrAH2, ssrAH1AcP, ssrADAcP, ssrAH2AcP and (B) D56A SsrB shows similar levels to that of the wild type, and higher than the ssrB mutant. Source data file: Figure 2—source data 1. (C) Beta-galactosidase activity of a sifA-lacZ chromosomal fusion was significantly lower in the ssrB null and the D56A SsrB mutant compared to the wild type. n = 3, Mean ± SD, p < 0.0001. Source data file: Figure 2—source data 2.
