Flexibility of the N-terminal α-helix of Salmonella FlhBC observed in MD simulations. (a) Key residues and vectors used for MD analysis in Table 2[link]. The vectors connecting residues 229–238, 238–256, 256–264, 265–269 and 238–264 are defined as V1–V5, respectively. (be) Structural variations of the N-­terminal α-helix during MD simulations when the globular domain is superimposed for (b) the wild-type FlhBC, (c) FlhBC Δ(281–285), (d) FlhBC AAAAA281–285 and (e) FlhBC PPPPP281–285. For each case, six snapshots were chosen based on the maximum and minimum values of D, θ14 and χ5 (see Table 2[link] for their definitions).
