Hammerhead ribozymes are the smallest known naturally occurring ribozymes which are capable of catalyzing the endonucleolytic trans-esterification of RNA. A recent re-examination of the catalytic properties of naturally-derived hammerhead ribozymes has resulted in a better understanding of the catalytic efficiency of this enzyme in vitro and in vivo. The minimal trans-cleaving hammerhead ribozyme has been a ubiquitous tool in both genomics and therapeutics research over the last twenty years and these new insights into hammerhead ribozyme biochemistry may offer hope for the generation of improved trans-cleaving ribozymes which function effectively in vivo. Next-generation hammerhead ribozymes may play an important role as therapeutic agents, as enzymes which tailor defined RNA sequences, as biosensors, and for applications in functional genomics and gene discovery.
