Biopolymers, 1999 The hammerhead ribozyme is an intriguing RNA molecule with the ability to serve as a catalyst to cleave sequence-specifically RNA molecules in an intermolecular reaction. Preferentially Mg(2+) is required for optimal activity by inducing the catalytically competent conformation and by possibly acting as an acid-base catalyst.

Robertson, Michael P. Bull, Jim On p. [614][1] of this issue, Wright and Joyce report the successful evolution of a catalytic ribozyme selected for its ability to perform ligation. In their Perspective, Ellington et al . comment on the advances in this study over previous efforts and what this work tells us about evolution.

The hammerhead ribozyme is a small RNA motif consisting of three helices that intersect at a conserved core. When correctly folded, the hammerhead ribozyme stimulates nearly complete cleavage of the phosphodiester chain at a defined internal site to give 2′,3′-cyclic and 5′-hydroxy termini. The cleavage rate is approx.

Ribozymes: the hairpin and Varkud ribozymes are related.
Rivista di biologia, 2003The hairpin ribozyme of plant virusoids and the Varkud ribozyme from a retroplasmid of fungal mitochondria show notable similarities in sequence and secondary structure. Some more distant inter-relationships appear to exist between this pair, the viroid/virusoid hammerhead and the hepatitis delta ribozyme.

RNA enzymes or ribozymes are receiving considerable attention for their potential use as highly specific inhibitors of gene expression. From the basic science perspective, the mechanisms by which ribozymes catalyze site-specific cleavage (and in some cases ligation) reactions provide exciting and active areas of scientific investigation.

The Novel Chemical Mechanism of the Twister Ribozyme.
Journal of the American Chemical Society, 2016We describe the multifactorial origins of catalysis by the twister ribozyme. We provide evidence that the adenine immediately 3' to the scissile phosphate (A1) acts as a general acid.

The selective inactivation of genes, in a tissue-specific or temporally controlled manner, is now an important requirement for the analysis of nervous system development and function. Hammerhead ribozymes--catalytic RNA enzymes that specifically bind to and then cleave target RNAs--may provide a way to meet this requirement, particularly for organisms ...

Ribozymes are structured RNA molecules that act as catalysts in different biological reactions. From simple genome cleaving activities in satellite RNAs to more complex functions in cellular protein synthesis and gene regulation, ribozymes play important roles in all forms of life.
