Catalytic RNAs, or ribozymes, are a fossil record of the ancient molecular evolution of life on Earth and still provide the essential core of macromolecule synthesis in all life forms today.
The tC19Z ribozyme can add up to 95 nucleotides with a fidelity of 0.0083 mutations/nucleotide. Attempts have been made to develop ribozymes as therapeutic agents, as enzymes which target defined RNA sequences for cleavage, as biosensors, and for applications in functional genomics and gene discovery.or example in self cleaving ribozyme RNAs, an in-line SN2 reaction is carried out using the 2â hydroxyl group as a nucleophile attacking the bridging phosphate and causing 5â oxygen of the N+1 base to act as a leaving group.
