Scientists from the University of California San Francisco (UCSF) have, for the first time, created a precise, molecular-level, 3D structure of how an odor molecule activates an odorant receptor in humans. The research focuses on an olfactory receptor, called OR51E2, and shows how it 'recognizes' the smell of cheese through certain molecular interactions that turn on the receptor.
