Extending the cleavage rules for the hammerhead ribozyme: mutating adenosine15.1 to inosine15.1 changes the cleavage site specificity from N16.2U16.1H17 to N16.2C16.1H17.

Abstract excerpt

In this paper, we show that an adenosine to inosine mutation at position 15.1 changes the substrate specificity of the hammerhead ribozyme from N16.2U16.1H17to N16.2C16.1H17(H represents A, C or U). This result extends the hammerhead cleavage triplet definition from N16.2U16.1H17to the more general N16.2Y16.1H17. Comparison of cleavage rates using I15.1ribozymes for NCH triplets and standard A15.1 ribozymes for...
