CHIMERIC tRNA LYS -RIBOZYME MOLECULES

摘要

The invention provides novel chimeric tRNALYS-ribozyme molecules that compete effectively with tRNALYS for HIV-1 reverse transcriptase binding sites. The chimeric human tRNALYS-ribozymes inhibit reverse HIV transcription by delivering inhibitors such as ribozymes of HIV-1 reverse transcriptase directly to the virion particle and render it non-functional. The chimeric molecules of the invention thus serve as highly specific non-toxic therapeutic agents. These chimeric molecules also reveal a novel, site specific RNA cleaving activity of HIV-1.
