NUCLEIC ACID ENZYME SHOWING ALLOSTERIC RNA-CLEAVING ACTIVITY ON TARGET RNA

摘要

A nucleic acid enzyme with allosteric RNA-cleaving activity on a target RNA. An expression vector containing a DNA coding for the nucleic acid enzyme. A method for producing the nucleic acid enzyme, in which an expression vector DNA containing a DNA encoding the nucleic acid enzyme is used as a template in the transcription to RNA. A pharmaceutical composition containing the nucleic acid enzyme or the expression vector containing the DNA coding for the nucleic acid enzyme as an effective component. A method for specifically cleaving target RNA by using the nucleic acid enzyme. <IMAGE>
