Single Mutation in Hammerhead Ribozyme Favors Cleavage Activity with Manganese over Magnesium [PDF]

open access: goldNon-Coding RNA, 2020
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

The structure and catalytic mechanism of a pseudoknot-containing hammerhead ribozyme [PDF]

open access: yesNature Communications
We have determined the crystal structure of a pseudoknot (PK)-containing hammerhead ribozyme that closely resembles the pistol ribozyme, with essentially identical secondary structure and connectivity. The activity is more sensitive to deletion of the G8

Life on Minerals: Binding Behaviors of Oligonucleotides on Zirconium Silicate and Its Inhibitory Activity for the Self-Cleavage of Hammerhead Ribozyme [PDF]

open access: goldLife, 2022
The role of minerals in the chemical evolution of RNA molecules is an important issue when considering the early stage of the Hadean Earth. In particular, the interaction between functional ribozymes and ancient minerals under simulated primitive ...

The ubiquitous hammerhead ribozyme. [PDF]

open access: yesRNA, 2012
The hammerhead ribozyme is a small catalytic RNA motif capable of endonucleolytic (self-) cleavage. It is composed of a catalytic core of conserved nucleotides flanked by three helices, two of which form essential tertiary interactions for fast self-scission under physiological conditions. Originally discovered in subviral plant pathogens, its presence

Hammerhead ribozyme activity and oligonucleotide duplex stability in mixed solutions of water and organic compounds [PDF]

open access: yesFEBS Open Bio, 2014
Nucleic acids are useful for biomedical targeting and sensing applications in which the molecular environment is different from that of a dilute aqueous solution. In this study, the influence of various types of mixed solutions of water and water-soluble

Enhanced RNA knockdown efficiency with engineered fusion guide RNAs that function with both CRISPR-CasRx and hammerhead ribozyme. [PDF]

open access: yesGenome Biol, 2023
Background CRISPR-Cas13 is a newly emerging RNA knockdown technology that is comparable to RNAi. Among all members of Cas13, CasRx degrades RNA in human cells with high precision and effectiveness.
