Extraordinarily slow binding of guanosine to the Tetrahymena group I ribozyme: Implications for RNA preorganization and function

The Tetrahymena ribozyme derived from the self-splicing group I intron binds a 5′-splice site analog (S) and guanosine (G), catalyzing their conversion to a 5′-exon analog (P) and GA. Herein, we show that binding of guanosine is exceptionally slow, limiting the reaction at near neutral pH. Our resul...
