Interactions of cytochrome C with N-acylated phosphatidylethanolamine lipids.

N-acylphosphatidylethanolamines (NAPEs) are naturally occurring derivatives of phosphatidylethanolmine (PE) in which the PE amino group is attached to an acyl chain. Given their occurrence in natural systems, there is interest in knowing the effect of NAPEs on membrane dynamic structure and function. This study examines the ability of NAPEs to affect the association of the cytochrome c and Zn-heme cytochrome c with the surface of bilayer membranes.
