Abstract

The light-energy transducing purple membrane within the cell membrane of the Halo-bacteria forms large patches (for a recent review see Henderson, 1977). It is composed of only one protein species called bacteriorhodopsin (bR) which comprises 75% of the dry weight of purple membrane (Oesterhelt and Stoeckenius, 1971). It contains approximately ten negatively charged lipid molecules per molecule of bR. Trimers of bR form a highly stable 2-D crystal belonging to the hexagonal system with p3 symmetry
