Transfer RNA splicing in Saccharomyces cerevisiae: defining the substrates.
The primary sequences of all the tRNA precursors which contain intervening sequences and which accumulate in the Saccharomyces cerevisiae rnal mutant are presented. A combination of DNA and RNA sequence analysis has led to elucidation of the primary sequence of four hitherto uncharacterized precursors. The location of the intervening sequence has in all cases been unambiguously determined by an...
متن کاملTransfer RNA post-transcriptional processing, turnover, and subcellular dynamics in the yeast Saccharomyces cerevisiae.
Transfer RNAs (tRNAs) are essential for protein synthesis. In eukaryotes, tRNA biosynthesis employs a specialized RNA polymerase that generates initial transcripts that must be subsequently altered via a multitude of post-transcriptional steps before the tRNAs beome mature molecules that function in protein synthesis. Genetic, genomic, biochemical, and cell biological approaches possible in the...
متن کاملThree adjacent transfer RNA genes in Escherichia coli.
A defective varphi80 transducing phage has been isolated that carries a small section of the E. coli chromosome from the region near argH (77 min). This phage contains three E. coli tRNA genes, termed glyTsu(+) (36), tyrT, and thrT. These genes specify the structures of tRNA(2) (Gly) (su(+) (36)) tRNA(2) (Tyr), and tRNA(3) (Thr), respectively. Induction of a single lysogen bearing this phage br...
متن کاملStudies on genetically altered transfer RNA species in Escherichia coli.
The study of tRNA molecules altered by a mutational event can lead to information in 3 important areas: (a) structure-function relationships in tRNA biochemistry; (ft) the genetics of tRNA; and (c) the physiological role of tRNA-isoaccepting species. For example, the elucidation of the structural alteration in a mutant tRNA species which reacts appreciably more slowly than normal tRNA in the en...
متن کاملSynthesis of stable RNA in stringent Escherichia coli cells in the absence of charged transfer RNA.
It has been possible to demonstrate the complete absence of either charged tRNA(Glu) or charged tRNA(Val) at 42 degrees by the use of two stringent strains of E. coli, one temperature-sensitive for glutamyl-tRNA synthetase and the other temperature-sensitive for valyl-tRNA synthetase. In both strains, stable RNA synthesis ceases, and guanosine tetraphosphate accumulates upon incubation at the n...
