Table 1. Calculated secondary structure of the NavSp channel in liposomes of different compositions based on SRCD measurements.

	“Guest “ Lipids
	PC	PG	PI
Helix	68±2	66±1	67±3
Sheet	4±1	7±2	6±2
Unordered	17±4	17±3	17±3

The percentage values listed are the average secondary structures calculated from several methods of analyses applied to the same data sets (the +/− values indicate the variations between algorithms). All liposomes include PE; the “guest” lipid is the second lipid present in the liposome sample.
