Critical domain interactions for type A RNase P RNA catalysis with and without the specificity domain. [PDF]

open access: yesPLoS ONE, 2018
The natural trans-acting ribozyme RNase P RNA (RPR) is composed of two domains in which the catalytic (C-) domain mediates cleavage of various substrates. The C-domain alone, after removal of the second specificity (S-) domain, catalyzes this reaction as

RNA interference approaches for treatment of HIV-1 infection. [PDF]

open access: yes, 2015
HIV/AIDS is a chronic and debilitating disease that cannot be cured with current antiretroviral drugs. While combinatorial antiretroviral therapy (cART) can potently suppress HIV-1 replication and delay the onset of AIDS, viral mutagenesis often leads to

A modern mode of activation for nucleic acid enzymes.

open access: yesPLoS ONE, 2007
Through evolution, enzymes have developed subtle modes of activation in order to ensure the sufficiently high substrate specificity required by modern cellular metabolism. One of these modes is the use of a target-dependent module (i.e. a docking domain)

Biochemical prevention and treatment of viral infections – A new paradigm in medicine for infectious diseases [PDF]

open access: yes, 2004
For two centuries, vaccination has been the dominating approach to develop prophylaxis against viral infections through immunological prevention. However, vaccines are not always possible to make, are ineffective for many viral infections, and also carry

Influence of a 3′ Terminal Ribozyme on AgoshRNA Biogenesis and Activity

open access: yesMolecular Therapy: Nucleic Acids, 2019
Short hairpin RNAs (shRNAs) can induce gene silencing via the RNA interference (RNAi) mechanism. We designed an alternative shRNA molecule with a relatively short base-paired stem that bypasses Dicer and instead is processed by the Argonaute 2 (Ago2 ...

RNA Back and Forth: Looking through Ribozyme and Viroid Motifs

open access: yesViruses, 2019
Current cellular facts allow us to follow the link from chemical to biochemical metabolites, from the ancient to the modern world. In this context, the “RNA world„ hypothesis proposes that early in the evolution of life, the ribozyme was ...

Force for ancient and recent life: viral and stem-loop RNA consortia promote life. [PDF]

open access: yes, 2014
Lytic viruses were thought to kill the most numerous host (i.e., kill the winner). But persisting viruses/defectives can also protect against viruses, especially in a ubiquitous virosphere. In 1991, Yarmolinsky et al.

Growth, Dissolution and Segregation of Genetically Encoded RNA Droplets by Ribozyme Catalysis

open access: yesAngewandte Chemie, EarlyView.
Ribozymes enable sequence‐encoded turnover of RNA droplet material, resulting in transiently active droplets that selectively segregate based on their genotype. This establishes a direct link between genetic information and droplet behavior, marking a step toward programmable, evolvable RNA‐based compartments with life‐like properties.

Evaluating target silencing by short hairpin RNA mediated by the group I intron in cultured mammalian cells

open access: yesBMC Biotechnology, 2011
Background The group I intron, a ribozyme that catalyzes its own splicing reactions in the absence of proteins in vitro, is a potential target for rational engineering and attracted our interest due to its potential utility in gene repair using trans ...

How RNA acts as a nuclease:some mechanistic comparisons in the nucleolytic ribozymes [PDF]

open access: yes, 2017
Recent structural and mechanistic studies have shed considerable light on the catalytic mechanisms of nucleolytic ribozymes. The discovery of several new ribozymes in this class has now allowed comparisons to be made, and the beginnings of mechanistic ...
