Figure 7
Phospholipid distribution (grey) in the diffraction plane. The difference Fourier map is based on the known structure of bacteriorhodopsin (Seiff et al., 1985) and on the intensity differences from anomalous diffraction of X-rays shown in Figs. 5 and 6. The unit cell contains three bacteriorhodopsin molecules. Their electron density projected on the plane of the membrane is indicated by the contour lines. |
