Results from DNase-I-protection assays provide direct evidence that SsrB binds at ssrA , although the binding sites lie within the .
In addition , the SsrB regulator also directly binds and autoregulates the ssrA promoters to activate their expression .
To confirm that SsrA-dependent phosphorylation was not required for SsrB-mediated regulation of bio-films , we examined biofilm formation of Salmonella strains possessing H867Q mutations in ssrA ( Kenney unpublished ) .
To confirm that SsrA-dependent phosphorylation was not required for SsrB-mediated regulation of bio-films , we examined biofilm formation of Salmonella strains possessing H867Q mutations in ssrA ( Walthers unpublished ) .
To confirm that SsrA-dependent phosphorylation was not required for SsrB-mediated regulation of bio-films , we examined biofilm formation of Salmonella strains possessing D739A mutations in ssrA ( Kenney unpublished ) .

To confirm that SsrA-dependent phosphorylation was not required for SsrB-mediated regulation of bio-films , we examined biofilm formation of Salmonella strains possessing H405Q mutations in ssrA ( Kenney unpublished ) .
To confirm that SsrA-dependent phosphorylation was not required for SsrB-mediated regulation of bio-films , we examined biofilm formation of Salmonella strains possessing H405Q mutations in ssrA ( Walthers unpublished ) .
To confirm that SsrA-dependent phosphorylation was not required for SsrB-mediated regulation of bio-films , we compared them to ssrA .
