Ribozymes that can be regulated by external stimuli

- Ribozyme activity can be regulated by chemical and physical stimuli.
- Aptazymes consist of RNA aptamers joined to ribozymes via a communication module.
- Ribozymes can work in a truly allosteric fashion.
- Ligand-dependent ribozymes are tools for diagnostics and control of gene expression.
- Allosteric ribozymes for sensing a specific ligand can be designed by bioinformatics.
