From: Retrozymes are a unique family of non-autonomous retrotransposons with hammerhead ribozymes that propagate in plants through circular RNAs

Fig. 1

Representation of the three possible hammerhead ribozyme (HHR) topologies. The conserved nucleotides involved in the catalytic center are boxed. Conserved loop-loop interactions are also indicated. Dotted and continuous lines refer to non-canonical and Watson-Crick base pairs, respectively. The three HHR types have been reported in prokaryotic/phage genomes, whereas only types I and III have been described in plants. Metazoan genomes mostly show type I HHRs
