Screening for Important Base Identities in the Hairpin Ribozyme by In Vitro Selection for Cleavage
Random mutagenesis followed by an in vitro selection procedure was shown to be capable of identifying important bases of the hairpin ribozyme for cleavage of an RNA target sequence.

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

Folding and catalysis by the hairpin ribozyme [PDF]
The hairpin ribozyme undergoes a site‐specific transesterification cleavage of the phosphodiester backbone. The natural form of the ribozyme is a four‐way helical junction, where two arms contain unpaired loops. This folds by pairwise coaxial stacking of helical arms, and a rotation into an antiparallel conformation in which there is close association ...

Antisense-based molecules targeting HIV-1 RNA have the potential to be used as part of gene or drug therapy to treat HIV-1 infection. In this study, HIV-1 RNA was screened to identify more conserved and accessible target sites for ribozymes based on the ...

The naturally occurring structure and biological functions of RNA are correlated, which includes hammerhead ribozymes. We proposed new variants of hammerhead ribozymes targeting conserved structural motifs of segment 5 of influenza A virus (IAV) (+)RNA ...

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 ...

The folding of the hairpin ribozyme: Dependence on the loops and the junction [PDF]
In its natural context, the hairpin ribozyme is constructed around a four-way helical junction. This presents the two loops that interact to form the active site on adjacent arms, requiring rotation into an antiparallel structure to bring them into proximity.

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

RNA Back and Forth: Looking through Ribozyme and Viroid Motifs
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 ...
