SequenceCraft: machine learning-based resource for exploratory analysis of RNA-cleaving deoxyribozymes

open access: yesBMC Bioinformatics
Background Deoxyribozymes or DNAzymes represent artificial short DNA sequences bearing many catalytic properties. In particular, DNAzymes able to cleave RNA sequences have a huge potential in gene therapy and sequence-specific analytic detection of ...

The Exosome Complex in Health and Disease: A Multifaceted Regulator of RNA Homeostasis

open access: yesExperimed
The RNA exosome complex is a multi-subunit ribonuclease complex that participates in RNA degradation, processing, and quality control. In recent years, mutations and dysregulation in the subunits of this complex, which play significant roles in RNA ...

Catalytic Role for RNA in DNA Replication [PDF]

open access: yesNature New Biology, 1972
THERE are two biochemical systems which probably evolved before the development of accurate polynucleotide-specified protein synthesis: these are the system for polynucleotide replication and the machinery of protein synthesis itself1, 2. Before accurately specified proteins became available, these processes were perhaps catalysed by polynucleotide ...

RNA Catalytic Activity as a Probe of Chaperone-Mediated RNA Folding [PDF]

open access: yes, 2013
For structured RNAs that possess catalytic activity, this activity provides a powerful probe for measuring the progress of folding and the effects of RNA chaperone proteins on the folding rate. The crux of this approach is that only the natively folded RNA is able to perform the catalytic reaction.

NSUN7 is a catalytically inactive RNA m5C methyltransferase essential for sperm flagellum assembly

open access: yesNature Communications
RNA 5-methylcytosine (m5C) is a widespread RNA modification mainly catalyzed by the NSUN family, whose dysfunction is linked to various diseases. Among NSUN1-7, all possessing motifs IV and VI essential for RNA m5C formation, NSUN7’s catalytic activity ...

Rational Design of an Orthogonal Pair of Bimolecular RNase P Ribozymes through Heterologous Assembly of Their Modular Domains

open access: yesBiology, 2019
The modular structural domains of multidomain RNA enzymes can often be dissected into separate domain RNAs and their noncovalent assembly can often reconstitute active enzymes.

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

open access: yesMolecules, 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.

Inhibition of HIV-1 Replication and Dimerization Interference by Dual Inhibitory RNAs

open access: yesMolecules, 2010
The 5’-untranslated region (5’UTR) of the HIV-1 RNA is an attractive target for engineered ribozymes due to its high sequence and structural conservation.

High-throughput mutagenesis reveals unique structural features of human ADAR1

open access: yesNature Communications, 2020
Human ADAR proteins are responsible for RNA editing, conversion of adenosine to inosine in double-stranded RNA. Here the authors report a previously unknown zinc ion-binding site in the catalytic domain of human ADAR1 using high throughput mutagenesis ...
