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.

Induction of ribozyme activity by anti-ribozyme oligonucleotides [PDF]
Nucleic Acids Symposium Series, 1999 A new type of hammerhead ribozyme, with cleavage activity enhanced by oligonucleotides, was constructed. Stem II of the ribozyme was substituted with a non complementary loop (loop II). The modified ribozyme exhibited negligible cleavage of a target RNA; however, it was converted to an active molecule in the presence of oligonucleotides which were ...

Communications Biology, 2023 Investigating gene function relies on the efficient manipulation of endogenous gene expression. Currently, a limited number of tools are available to robustly manipulate endogenous gene expression between “on” and “off” states. In this study, we insert a

A RNase P Ribozyme Inhibits Gene Expression and Replication of Hepatitis B Virus in Cultured Cells
Microorganisms, 2023 Hepatitis B virus (HBV), an international public health concern, is a leading viral cause of liver disease, such as hepatocellular carcinoma. Sequence-specific ribozymes derived from ribonuclease P (RNase P) catalytic RNA are being explored for gene ...

Biology, 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 ...

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

Inhibition of human cytomegalovirus immediate early gene expression and growth by a novel RNase P ribozyme variant. [PDF]
PLoS ONE, 2017 We have previously engineered new RNase P-based ribozyme variants with improved in vitro catalytic activity. In this study, we employed a novel engineered variant to target a shared mRNA region of human cytomegalovirus (HCMV) immediate early proteins 1 ...

The prebiotic evolutionary advantage of transferring genetic information from RNA to DNA. [PDF]
, 2011 In the early 'RNA world' stage of life, RNA stored genetic information and catalyzed chemical reactions. However, the RNA world eventually gave rise to the DNA-RNA-protein world, and this transition included the 'genetic takeover' of information storage ...

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 ...

The Origin of Life: Models and Data. [PDF]
, 2017 A general framework for conventional models of the origin of life (OOL) is the specification of a 'privileged function.' A privileged function is an extant biological function that is excised from its biological context, elevated in importance over other
