Table 3.

Frequency of interaction between TM helix polar or charged side chains and phospholipid headgroups observed in the last 10 ns of restrained MD^a

	S1/M1	S1/M2	S2/M1	S2/M2
Tyr-25	0.91	0.92	0.89	0.93
Tyr-40	0.81	0.73	0.61	0.95
Ser-41	0.95	0.90	0.62	0.82
Arg-44	1.00	1.00	1.00	0.96
Lys-45	0.77	0.96	0.77	0.93

The interaction occurs when any heavy atom of a particular residue’s side chain is within 4 Å of a lipid headgroup atom.
