FIGURE 7

Sideview (A) and topview (B) of the simulated PSM bilayer in the liquid crystalline state. The frame was isolated from the MD trajectory obtained with the FF1 parameters (at 8 ns). A hydrogen-bonded cluster formed by eight lipids is shown as a solid line. Dashed black lines indicate the intermolecular hydrogen bonds. In (C) the residue PSM 59 from the cluster is represented together with all the intermolecular hydrogen bonds it formed. For the lipid-water-lipid hydrogen bonds only the bridging waters are reproduced. The donors and acceptors of the surrounding lipids that participated in direct lipid-lipid hydrogen bonds with PSM 59 are depicted as spheres.
