Figure 4.
Pseudoatomic structure of the SPP1 connector. Gp6 (blue), gp15 (magenta), and gp16 (green) structures resulting from separate docking in the EM connector maps were placed together in the whole-connector reconstruction and refined by using UROX (Cc = 55.3). Side (A) and cut open (B and C) views of the connector are shown. The electrostatic potential surfaces (C) were calculated with PBEQ-Solver (38).
