Labeling of Membrane Complexes for Electron Microscopy
Résumé
Localization of specific subunits or domains of interest inside protein complexes can be challenging, especially for membrane machineries. The amphipatic nature of their subunits and their modular organization results in difficult genetic manipulation and instability upon purification. Here, we present different labeling approaches that have been demonstrated successful in the structural characterization of large membrane complexes.
