Minimal twister sister-like self-cleaving ribozymes in the human genome revealed by deep mutational scanning [PDF]
Despite their importance in a wide range of living organisms, self-cleaving ribozymes in the human genome are few and poorly studied. Here, we performed deep mutational scanning and covariance analysis of two previously proposed self-cleaving ribozymes ...

Computational De Novo Design of Group II Introns Yields Highly Active Ribozymes. [PDF]
Group II Introns (G2Is) are large self‐splicing ribozymes with promising biotechnological applications. This study utilized RNA inverse folding to design three novel G2Is. The designed intron Arq.I2, an unexpectedly proficient ribozyme, self‐splices not only in vitro, but also in Escherichia coli cells.

Single Mutation in Hammerhead Ribozyme Favors Cleavage Activity with Manganese over Magnesium
Hammerhead ribozymes are one of the most studied classes of ribozymes so far, from both the structural and biochemical point of views. The activity of most hammerhead ribozymes is cation-dependent. Mg2+ is one of the most abundant divalent cations in the
