(a) Crystal structures of GDP-bound (blue) and GTP-bound or GMPPNP-bound (red) states of FlhF, Ffh and FtsY. Comparison reveals conserved rearrangements in the G2 and G3 elements, as well as larger modifications in the G4 and G5 regions within the SRP GTPases. (b) Close-up of the superimposition of the N-domain helical bundle. Topological changes depending on the nucleotide-binding state are conserved within this family of GTPases.
