Figure 4
Bending of the α3 helix does not occur in previous crystal structures. Superpositions of AscX₃₁–YscY with (a) AscX₄₉–YscY (PDB entry 8arb), (b) YscX₅₀–YscY (PDB entry 7qih), (c) YscX₃₂–YscY (PDB entry 7qii) and (d) YscX₃₂–YscY engaging the cytosolic domain of the export gate YscV (orange surface; PDB entry 7qij) are shown.
