TABLE 3.

Deviation of structural parameters of the fluid phase of E. coli total lipid extracts at 25 °C and of the respective cubic phases after one heating-cooling cycle in the presence of LF11-derived peptides (lipid-to-peptide molar ratio of 25:1

Structural parameters for E. coli total lipids in the absence of peptides are as follows: phosphate-to-phosphate distance, d_pp = 40.5 Å; lattice spacing, Pn3m = 151 Å and Im3m = 194 Å. ND means not detected.
