| Abstract: | The nanoparameters of an actinobacterial membrane have been estimated by neutron diffraction on multilamellar lipid membranes. The lamellar repeat distance in a partly hydrated membrane prepared with the phospholipid fraction from Streptomyces hygroscopicus is 85.8 ± 0.5°C and decreases to 83.5 ± 0.5 0°C. Some lipids are not incorporated into the bilayer and form a liquid phase of micelles 54.2 ± 0.2 |
