Guanosine binding to the Tetrahymena ribozyme: thermodynamic coupling with oligonucleotide binding.
The L-21 Sca I ribozyme derived from the group I intron of Tetrahymena thermophila pre-rRNA catalyzes an endonuclease reaction analogous to the first step of self-splicing. Guanosine (G) is bound by the ribozyme, and its 3'-hydroxyl group acts as the nucleophile. Here, we provide evidence that...
