Mitochondrial tRNA mutations - Clinical and functional perturbations
(2007)
During the last decade, there has been a progressive accumulation of reports that connect the identification of specific mitochondrial tRNA gene mutations to severe disorders in human. As a result, mitochondrial tRNA genes ...
A 40.7 kDa Rpp30/Rpp1 homologue is a protein subunit of Dictyostelium discoideum RNase P holoenzyme
(2007)
RNase P is an essential and ubiquitous endonuclease that mediates the maturation of the 5' ends of all precursor tRNA molecules. The holoenzyme from Dictyostelium discoideum possesses RNA and protein subunits essential for ...
Inhibition of human poly(A)-specific ribonuclease (PARN) by purine nucleotides: kinetic analysis
(2009)
Poly(A)-specific ribonuclease (PARN) is a cap-interacting and poly(A)-specific 3'-exoribonuclease that efficiently degrades mRNA poly(A) tails. Based on the enzyme's preference for its natural substrates, we examined the ...
A single tRNA base pair mediates bacterial tRNA-dependent biosynthesis of asparagine
(2006)
In many prokaryotes and in organelles asparagine and glutamine are formed by a tRNA-dependent amidotransferase (AdT) that catalyzes amidation of aspartate and glutamate, respectively, mischarged on tRNA(Asn) and tRNA(Gln). ...
Competitive Inhibition of Human Poly(A)-Specific Ribonuclease (PARN) by Synthetic Fluoro-Pyranosyl Nucleosides
(2009)
Poly(A)-specific ribonuclease (PARN) is a cap-interacting deadenylase that mediates, together with other exonucleases, the eukaryotic mRNA turnover and thus is actively involved in the regulation of gene expression. ...
