The Kiss Switch Brings Inactive R3C Ligase Ribozyme Back to Life [PDF]

open access: goldBiology, 2018
R3C ligase ribozyme catalyzes the nucleophilic attack by a 3′-hydroxyl on a 5′-α-phosphorus of triphosphates to form a 3′-5′-phosphodiester bond. In the present study, although the truncation of R3C ribozyme was accompanied by a large reduction in ...

Prebiotic Factors Influencing the Activity of a Ligase Ribozyme [PDF]

open access: goldLife, 2017

Reconciling Ligase Ribozyme Activity with Fatty Acid Vesicle Stability [PDF]

open access: goldLife, 2014
The “RNA world” and the “Lipid world” theories for the origin of cellular life are often considered incompatible due to the differences in the environmental conditions at which they can emerge.

Development of Allosteric Ribozymes for ATP and l-Histidine Based on the R3C Ligase Ribozyme [PDF]

open access: goldLife
During the evolution of the RNA, short RNAs are thought to have joined together to form long RNAs, enhancing their function as ribozymes. Previously, the artificial R3C ligase ribozyme (73 nucleotides) was successfully reduced to 46 nucleotides; however,

A cis-acting ligase ribozyme generates circular RNA in vitro for ectopic protein functioning [PDF]

open access: goldNature Communications
Delivering synthetic protein-coding RNA bypassing the DNA stage for ectopic protein functioning is a novel therapeutic strategy. Joining the linear RNA head-to-tail covalently could be a state-of-the-art strategy for functioning longer.

Molecular Anatomy of the Class I Ligase Ribozyme for Elucidation of the Activity-Generating Unit [PDF]

open access: goldBiology, 2023
The class I ligase ribozyme consists of 121 nucleotides and shows a high catalytic rate comparable to that found in natural proteinaceous polymerases. In this study, we aimed to identify the smaller active unit of the class I ligase ribozyme comprising ...

RNA ligase ribozymes with a small catalytic core [PDF]

open access: goldScientific Reports, 2023
Catalytic RNAs, or ribozymes, catalyze diverse chemical reactions that could have sustained primordial life in the hypothetical RNA world. Many natural ribozymes and laboratory evolved ribozymes exhibit efficient catalysis mediated by elaborate catalytic

Development of a Functionally Minimized Mutant of the R3C Ligase Ribozyme Offers Insight into the Plausibility of the RNA World Hypothesis [PDF]

open access: goldBiology, 2014
The R3C ligase ribozyme is an artificial ligase ribozyme produced by modification of the ribozyme that lacks cytidine. Here, we attempted to modify the original R3C ribozyme (73 nucleotides) by reducing the number of nucleotides while maintaining the ...

Template-directed ligation of tethered mononucleotides by t4 DNA ligase for kinase ribozyme selection. [PDF]

open access: goldPLoS ONE, 2010
BACKGROUND: In vitro selection of kinase ribozymes for small molecule metabolites, such as free nucleosides, will require partition systems that discriminate active from inactive RNA species.

Generation and Development of RNA Ligase Ribozymes with Modular Architecture Through “Design and Selection” [PDF]

open access: goldMolecules, 2010
In vitro selection with long random RNA libraries has been used as a powerful method to generate novel functional RNAs, although it often requires laborious structural analysis of isolated RNA molecules.
