Ribozymes have been proposed and developed for the treatment of disease through gene therapy. One major challenge of using RNA-based enzymes as a therapeutic is the short half-life of the catalytic RNA molecules in the body. To combat this, the 2’ position on the ribose is modified to improve RNA stability. One … Visa mer Ribozymes (ribonucleic acid enzymes) are RNA molecules that have the ability to catalyze specific biochemical reactions, including RNA splicing in gene expression, similar to the action of protein enzymes. The 1982 discovery … Visa mer Before the discovery of ribozymes, enzymes—which are defined as catalytic proteins —were the only known biological catalysts. In 1967, Carl Woese, Francis Crick, and Leslie Orgel were the first to suggest that RNA could act as a catalyst. This idea was based … Visa mer Although ribozymes are quite rare in most cells, their roles are sometimes essential to life. For example, the functional part of the ribosome, the biological machine that translates RNA into proteins, is fundamentally a ribozyme, composed of RNA tertiary structural motifs Visa mer Well-validated naturally occurring ribozyme classes: • GIR1 branching ribozyme • glmS ribozyme • Group I self-splicing intron • Group II self-splicing intron – Spliceosome is likely derived from Group II self-splicing ribozymes.
