Photoactivation of rhodopsin (Rho), a G protein-coupled receptor, causes conformational changes that provide a specific binding site for the rod G protein, G(t). In this work we employed structural mass spectrometry techniques to elucidate the structural changes accompanying transition of ground state Rho to photoactivated Rho (Rho(∗)) and in the pentameric complex between dimeric Rho(∗) and heterotrimeric G(t). Observed differences in hydroxyl radical labeling and deuterium uptake between Rho(∗ ...[more]
