Comparison of the α-TTP-α-Tol-PI(3,4)P2 complex n differentstates. (A) the scaffold of the partially-bound structure from X-ray scattering [PDB: 3W67 (Kono et al., 2013), in green cartoon], is superimposed to the fully bound structure obtained from our MD simulations (orange cartoon) and to the closed X-ray structure with fully bound α-Tol [PDB: 1OIP (Meier et al., 2003)] (blue). (B) the inset report a zoom of the mobile gate helix (N198-K217) and the G162-L183 segment with which the mobile gate is in contact in closed structures. (C) Contact maps between the G162-L183 and the N198-K217 segments in the intermediate state captured in PDB: 3W67 (Kono et al., 2013) (C1), in the α-TTP-α-Tol complex (PDB: 1OIP, Meier et al., 2003, C2), and in the relaxed structure from MD simulations for the α-TTP-PI(3,4)P2 complex (C3) and for the α-TTP-PI(4,5)P2 complex (C4).
