Contrast Variation Small Angle Neutron Scattering (SANS) has provided important insights into the biogenesis of membrane proteins in Gram-negative bacteria. Their cell envelope consists of two membranes, which differ with respect to their lipid composition, but also in the structure of their integral membrane proteins. Importantly, the latter are synthesised in the cytoplasm and therefore have to be transported to their correct membrane. SANS analysis of integral membrane translocons and soluble chaperones involved in this process have clarified the molecular basis of biological function, as well as revealed unexpected conserved mechanisms present in eukaryotic organisms.
