NMR-based detection of hydrogen/deuterium exchange in liposome-embedded membrane proteins.
Membrane proteins play key roles in biology. Determination of their structure in a membrane environment, however, is highly challenging.

| Summary: | Membrane proteins play key roles in biology. Determination of their structure in a membrane environment, however, is highly challenging. To address this challenge, we developed an approach that couples hydrogen/deuterium exchange of membrane proteins to rapid unfolding and detection by solution-state NMR spectroscopy. We show that the method allows analysis of the solvent protection of single residues in liposome-embedded proteins such as the 349-residue Tom40, the major protein translocation pore in the outer mitochondrial membrane, which has resisted structural analysis for many years. |
