FIG 7.

RsmA is active in a mucA22 mutant strain. (A) Leader/translational fusion lacUV5 hcnA-lacZ (above graph) was introduced into the indicated strains in single copy, grown for 8 h in LB broth, and assayed for β-galactosidase activity. Significant differences from the wild type were determined using a one-way analysis of variance and Tukey's posttest. Triple asterisks indicate P values of <0.0001. (B) Leader/translational fusion lacUV5 tssA1-lacZ (above graph) was introduced into the indicated strains in single copy, grown for 8 h in LB broth, and assayed for β-galactosidase activity. Significant differences from the wild type were determined using a one-way analysis of variance and Tukey's posttest. Triple asterisks indicate P values of <0.0001. All leader/translational fusions were assayed in triplicate three times.
