title: Caged RNase: photoactivation of the enzyme from perfect off-state by site-specific incorporation of 2-nitrobenzyl moiety.
abstract: Photo-triggered activation of semisynthetic Ribonuclease S' from a perfect off-state was successfully carried out by incorporation of photo-labile caged moiety into a proximity to the active site.
