The Escherichia coli GcvB sRNA Uses Genetic Redundancy to Control cycA Expression
Figure 6
GcvB represses cycA mRNA by an antisense mechanism. WT and ΔgcvB λcycA-lacZ, -lacZ, -lacZ, and -lacZ lysogens transformed with the indicated plasmids were grown in LB (+Amp for transformants) to mid-log phase and assayed for β-galactosidase.
