Snapshot of anionic lipid interacting with nearby charged protein residues. Coordinate frames for PS1 (a) and PS2 (b) in, O1 like orientation; for PI1 (c), PI3 (d), and PI4 (e) in, O3 like orientation. Na+ ions that were found to mediate the interaction of negative residues with anionic lipids in (b-d) are shown as yellow beads. See also Table S2.
