  • Inhibition of RNase P cleavage by aminoglycosides
  • 1999

    • A number of aminoglycosides have been reported to interact and interfere with the function of various RNA molecules. Among these are 16S rRNA, the group I intron, and the hammerhead ribozymes. In this report we show that cleavage by RNase P RNA in the absence as well as in the presence of the RNase P protein is inhibited by several aminoglycosides. Among the ones we tested, neomycin B was found to be the strongest inhibitor with a Ki value in the micromolar range (35 microM). Studies of lead(II)-induced cleavage of RNase P RNA suggested that binding of neomycin B interfered with the binding of divalent metal ions to the RNA. Taken together, our findings suggest that aminoglycosides compete with Mg2+ ions for functionally important divalent metal ion binding sites. Thus, RNase P, which is an essential enzyme, is indeed a potential drug target that can be used to develop new drugs by using various aminoglycosides as lead compounds.
