WebbTo create an allosteric ribozyme, a ribozyme is connected via a “communication module” to an aptamer that is specific for a certain ligand. The communication module couples the aptamer–ligand interaction to ribozyme activity ( Robertson and Ellington 2000 ; Kertsburg and Soukup 2002 ), usually via up-regulation but sometimes via inhibition ( Tang and … WebbDoherty EA, Doudna JA (2000) Ribozyme structures and mechanisms.
