1982K. Kruger et al. in Cell XXXI. 154/2 Because the IVS [sc. intervening sequence] RNA is not an enzyme but has some enzyme-like characteristics, we call it a ribozyme. 1983Jrnl. Molecular Biol. CLXVII. 602 The secondary structure model developed for fungal mitochondrial introns..provides a clear rationalization for the structures that make up the active site of the ‘ribozyme’. 1987Nature 19 Feb. 677/2 First, snRNPs [sc. small nuclear ribonucleoprotein particles] may be ‘ribozymes’, by analogy with RNase P where the RNA component of a ribonucleoprotein complex is able to cleave transfer RNA precursors at a specific site. 1988Daily Tel. 20 Aug. 4/1 Ribozymes enable scientists to chop up RNA in a predictable way, a trick which could be used to destroy viruses such as polio or Aids. |
