Ribozymes: the hairpin and Varkud ribozymes are related.
The 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.
