Design, characterization and testing of tRNA3Lys-based hammerhead ribozymes.
A hammerhead ribozyme targeted against the HIV-1 env coding region was expressed as part of the anticodon loop of human tRNA3Lys without sacrificing tRNA stability or ribozyme catalytic activity. These tRNA-ribozymes were isolated from a library which was designed to contain linkers (sequences connecting the ribozyme to the anticodon loop) of random sequence and variable length. The ribozyme ta...
متن کاملIntronic hammerhead ribozymes in mRNA biogenesis
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 along the tree of life. In eukaryotes, most of the genomic HHRs se...

متن کاملRibozymes: The hammerhead swings into action
A new crystal structure of a modified hammerhead ribozyme reveals an intermediate conformation that may explain discrepancies between previous structures and the required orientation of the labile bond in the ribozyme's active site.
