Fig. 4. Gram-positive Hfq proteins do not recognize A-rich target RNA.
(a) Binding of FAM-labeled rA18 RNA to the distal face of Hfq was measured by fluorescence anisotropy, as previously described (15). (b) Fractional binding versus [Hfq6] was measured and fitted to a two-state Hill equation as described in Fig. 3b.
