The hammerhead ribozyme is a RNA molecule motif that catalyzes reversible cleavage and joining reactions at a specific site within an RNA molecule.
A ribozyme is a polyribonucleotide (RNA molecule) with enzymatic activity. They are sometimes also referred to as RNA enzymes however, to avoid confusion with ribonucleoproteins in which the RNA lacks catalytic activity, ribozyme is generally preferred. Ribozymes have been found in every known cell and are essential to cell functioning. The most well known example of an essential ribozyme is the 28S rRNA (called the 23S rRNA in prokaryotes), which carries out the aminoacyltransferase (peptide-lengthening) activity of ribosomes.
