Structure determination of membrane proteins is one of the challenges in structural biology. While X-ray crystallography remains the workhorse technique in these efforts, innovative use of X-ray scattering could provide complementary information to help elucidate the structures and function of these proteins. I will summarize the scientific results and technical developments in past studies of membrane fusion and pore-forming peptides utilizing substrate-supported multi-layered lipid membranes. I will then describe the recent progress using substrate-supported single-bilayers, which promise a more versatile platform for structural biologists to explore the structure of membrane proteins in near native environments, and how they interact with each other and with the lipid membrane. Expected advances with the advent of the new beamlines at NSLS-II will also be discussed.
