Abstract

Spatiotemporal modulation of individual protein subdomains with light as the trigger signal becomes possible by using bivalent aptamers and introducing photolabile 'caging groups' to switch individual aptamer modules ON or OFF differentially. To the best of our knowledge, this is the first study to show that it is possible to modulate individual domain activity in aptamers, and thus also domain activity in proteins, with light.
