A Faster Triphosphorylation Ribozyme. [PDF]

PLoS ONE, 2015
In support of the RNA world hypothesis, previous studies identified trimetaphosphate (Tmp) as a plausible energy source for RNA world organisms. In one of these studies, catalytic RNAs (ribozymes) that catalyze the triphosphorylation of RNA 5'-hydroxyl ...

Fluorescence Polarization for Monitoring Ribozyme Reactions in Real Time

BioTechniques, 2000
Fluorescence polarization has been used recently to monitor diverse macromolecular interactions. In this report, the application of fluorescence polarization has been extended to monitor ribozyme reactions in real time.

Arginine cofactors on the polymerase ribozyme. [PDF]

PLoS ONE, 2011
The RNA world hypothesis states that the early evolution of life went through a stage in which RNA served both as genome and as catalyst. The central catalyst in an RNA world organism would have been a ribozyme that catalyzed RNA polymerization to ...

RNA-peptide interactions tune the ribozyme activity within coacervate microdroplet dispersions [PDF]

Nature Communications
Membrane-free complex coacervate microdroplets are compelling models for primitive compartmentalisation with the ability to form from biological molecules.

Ribozyme-Mediated Knockdown of lncRNA Gene Expression in Drosophila [PDF]

Bio-Protocol
Long noncoding RNAs (lncRNAs) are increasingly understood to play important roles in cell biology, development, and disease, though the vast majority of annotated lncRNAs have yet to be functionally characterized.

Structural Expansion of Catalytic RNA Nanostructures through Oligomerization of a Cyclic Trimer of Engineered Ribozymes

Molecules, 2023
The multimolecular assembly of three-dimensionally structured proteins forms their quaternary structures, some of which have high geometric symmetry. The size and complexity of protein quaternary structures often increase in a hierarchical manner, with ...

RNase P Ribozyme Effectively Inhibits Human CC-Chemokine Receptor 5 Expression and Human Immunodeficiency Virus 1 Infection

Zoonotic Diseases, 2023
Developing novel antiviral agents and approaches is essential for the treatment against human and zoonotic viruses. We had previously produced RNase P-based ribozyme variants capable of efficiently cleaving mRNA in vitro.

A convolutional neural network for the prediction and forward design of ribozyme-based gene-control elements

eLife, 2021
Ribozyme switches are a class of RNA-encoded genetic switch that support conditional regulation of gene expression across diverse organisms. An improved elucidation of the relationships between sequence, structure, and activity can improve our capacity ...

Effective inhibition of human immunodeficiency virus 1 replication by engineered RNase P ribozyme. [PDF]

PLoS ONE, 2012
Using an in vitro selection procedure, we have previously isolated RNase P ribozyme variants that efficiently cleave an mRNA sequence in vitro. In this study, a variant was used to target the HIV RNA sequence in the tat region.

Catalytic RNA Oligomers Formed by Co-Oligomerization of a Pair of Bimolecular RNase P Ribozymes

Molecules, 2022
Naturally occurring ribozymes with a modular architecture are promising platforms for construction of RNA nanostructures because modular redesign enables their oligomerization.
