Membrane-binding constants for SCAMP-derived peptides

Peptide PC (K, M−1) PC/PS (3∶1) (K, M−1)
D-SL 20 15
E-SL 328 >104
F-SL 65 53

Membrane-binding constants determined for these peptides have an error of 10–20%. We were not able to make an accurate prediction of the binding of peptide E in PC/PS with EPR because the concentration of peptide needed for the assay significantly alters the membrane charge density at low lipid concentrations.
