A new technique could revolutionize our understanding of how proteins do their jobs and guide the design of proteins for specific purposes.
The technique involves tagging two spots on the protein and tracking the distance between these labels as the protein unfolds and refolds.
The wobbling, or "precession" of the gadolinium ion is influenced by the proximity of the other tag, which has its own magnetic field generating its own field.
Scientists at University of California - Santa Barbara have developed a new technique to film proteins in motion.
TiGGER uses a light-activated protein called AsLOV2 to track biochemical processes in living cells using fluorescence, much like a highlighter under a black light.
LOV proteins enable scientists to use light as a "remote control" for a whole host of molecular processes.
