A hammerhead ribozyme selects mechanically stable conformations for catalysis against viral RNA [PDF]

open access: yesCommunications Biology
Ribozymes, widely found in prokaryotes and eukaryotes, target nucleic acids and can be engineered as biotechnical tools or for gene regulation or immune therapy. Among them, hammerhead is the smallest and best characterized ribozyme.

Long-term Expression of Apolipoprotein B mRNA-specific Hammerhead Ribozyme via scAAV8.2 Vector Inhibits Atherosclerosis in Mice

open access: yesMolecular Therapy: Nucleic Acids, 2013
Target substrate-specific hammerhead ribozyme cleaves the specific mRNA efficiently and results in the inhibition of gene expression. In humans, overproduction of apolipoprotein B (apoB) is positively associated with premature coronary artery diseases ...

Intronic hammerhead ribozymes in mRNA biogenesis [PDF]

open access: bronzebchm, 2012
Abstract Small self-cleaving ribozymes are a group of natural RNAs that are capable of catalyzing their own and sequence-specific endonucleolytic cleavage. One of the most studied members is the hammerhead ribozyme (HHR), a catalytic RNA originally discovered in subviral plant pathogens but recently shown to reside in a myriad of genomes

Eukaryotic penelope-like retroelements encode hammerhead ribozyme motifs. [PDF]

open access: yesMol Biol Evol, 2014
Small self-cleaving RNAs, such as the paradigmatic Hammerhead ribozyme (HHR), have been recently found widespread in DNA genomes across all kingdoms of life.

Effective suppression of Dengue fever virus in mosquito cell cultures using retroviral transduction of hammerhead ribozymes targeting the viral genome [PDF]

open access: goldVirology Journal, 2009
Outbreaks of Dengue impose a heavy economic burden on developing countries in terms of vector control and human morbidity. Effective vaccines against all four serotypes of Dengue are in development, but population replacement with transgenic vectors ...

The unforeseeable hammerhead ribozyme [PDF]

open access: yesF1000 Biology Reports, 2009
Despite its small size, the complex behavior of the hammerhead ribozyme keeps surprising us, even more than 20 years after its discovery. Here, we summarize recent developments in the field, in particular the discovery of the first split hammerhead ...

Discovery of novel hammerhead, twister, and DVRz-associated circular RNAs in Vitaceae, Solanaceae, and Rosaceae [PDF]

open access: yesmSystems
Viroids and viroid-like exogenous circular RNAs (ex-circRNAs) are small infectious RNA agents capable of autonomous replication within host cells, independent of any helper virus.

Capturing hammerhead ribozyme structures in action by modulating general base catalysis. [PDF]

open access: yesPLoS Biology, 2008
We have obtained precatalytic (enzyme-substrate complex) and postcatalytic (enzyme-product complex) crystal structures of an active full-length hammerhead RNA that cleaves in the crystal.

Phylogenetic footprinting of non-coding RNA: hammerhead ribozyme sequences in a satellite DNA family of Dolichopoda cave crickets (Orthoptera, Rhaphidophoridae)

open access: yesBMC Evolutionary Biology, 2010
Background The great variety in sequence, length, complexity, and abundance of satellite DNA has made it difficult to ascribe any function to this genome component.

Design and Preparation of a Multimeric Self-Cleaving Hammerhead Ribozyme

open access: goldBioTechniques, 1997
The activity of a ribozyme can be impaired by additional sequences at the 5′ and 3′ termini of the catalytic sequence. To approach this problem, a system was designed that minimizes sequences upstream and downstream from active regions of a hammerhead ...
