Fig. 1.

MD simulation of four almost completely helical trans-SNARE complexes bridging a vesicle and a flat bilayer and close to the center of the interface. A slice of the system after 857 ns of simulation at 310 K is shown. Lipids and proteins are shown as stick models with nitrogen atoms in dark blue, oxygens in red, phosphorus in orange, and carbon atoms in yellow for the vesicle, light blue for the flat bilayer and salmon for the SNARE complex except for those of the jxt linkers, which are in slate. The same color-coding was used in all the figures except when noted otherwise. The SNARE complexes are in addition represented by ribbon diagrams.
