Identity elements of archaeal tRNA.
Features unique to a transfer-RNA are recognized by the corresponding tRNA-synthetase. Keeping this in view we isolate the discriminating features of all archaeal tRNA. These are our identity elements. Further, we investigate tRNA-characteristics that delineate the different orders of Archaea.
متن کاملIdentified Hybrid tRNA Structure Genes in Archaeal Genome
Background: In Archaea, previous studies have revealed the presence of multiple intron-containing tRNAs and split tRNAs. The full unexpurgated analysis of archaeal tRNA genes remains a challenging task in the field of bioinformatics, because of the presence of various types of hidden tRNA genes in archaea. Here, we suggested a computational method that searched for widely separ...
متن کاملIdentity elements of tRNA(Thr) towards Saccharomyces cerevisiae threonyl-tRNA synthetase.
Identity elements of tRNA(Thr) towards Saccharomyces cerevisiae threonyl-tRNA synthetase were examined using in vitro transcripts. By mutation studies, a marked decrease in aminoacylation with threonine showed that the first base pair in the acceptor stem and the second and third positions of the anticodon are major identity elements of tRNA(Thr), which are essentially the same as those of Esch...
متن کاملArchaeal extrachromosomal genetic elements.
SUMMARY Research on archaeal extrachromosomal genetic elements (ECEs) has progressed rapidly in the past decade. To date, over 60 archaeal viruses and 60 plasmids have been isolated. These archaeal viruses exhibit an exceptional diversity in morphology, with a wide array of shapes, such as spindles, rods, filaments, spheres, head-tails, bottles, and droplets, and some of these new viruses have ...
متن کاملArchaeal aminoacyl-tRNA synthesis: diversity replaces dogma.
Accurate aminoacyl-tRNA synthesis is essential for faithful translation of the genetic code and consequently has been intensively studied for over three decades. Until recently, the study of aminoacyl-tRNA synthesis in archaea had received little attention. However, as in so many areas of molecular biology, the advent of archaeal genome sequencing has now drawn researchers to this field. Invest...
