In this paper, we show that an adenosine to inosine mutation at position 15.1 changes the substrate specificity of the hammerhead ribozyme from N16.2U16.1H17 to N16.2C16.1H17 (H represents A, C or U). This result extends the hammerhead cleavage triplet definition from N16.2U16.1H17 to the more general N16.2Y16.1H17. Comparison of cleavage rates using I15.1 ribozymes for NCH triplets and standard A15.1 ribozymes for NUH triplets under single turnover conditions shows similar or slightly enhanced levels of reactivity for the I15.1-containing structures. The effect of I15.1 substitution was also...
