Membrane lipid composition defines membrane protein spectrum

In addition to glycerophospholipids, bacterial membranes often include amino acid-containing acyloxyacyl lipids. The functional implications of these aminolipids are largely un-known. However, a recent study by Stirrup et al. expands our under-standing and shows that they are major determinants for membrane properties and the relative abun-dance of distinct membrane pro-teins in bacterial membranes.
