Ribozyme enzyme and RNA, molecular model. Ribozymes are RNA (ribonucleic acid) molecules that catalyse certain biochemical reactions. Until their discovery in the 1980s it was thought only proteins had this ability. Most ribozymes catalyse their own cleavage, or that of other RNAs, but some also have roles within ribosomes, the location of protein synthesis. This conformation shows a minimal hairpin ribozyme in its transition state.
