Fractionation of Yeast Amino Acid-Acceptor Ribonucleic Acids by Countercurrent Distribution*?
Considerable interest has developed in recent years in the separation of the amino acid-specific “soluble’‘-fraction ribonucleic acids because of the probable role of these RNAs in protein biosynthesis (l-5) and because the elucidation of the structures of the different amino acid-specific RNAs may lead to an understanding of the mechanism of information transfer by nucleic acids. Preliminary s...

متن کاملStudies on the Chemical Structure of Yeast Amino Acid Acceptor Ribonucleic Acids.
Elucidation of the nucleotide sequence of amino acid acceptor ribonucleic acid may reveal the structural basis of its amino acid specificity. The task appears feasible in the near future because of the low molecular weight attributed to S-RNA’ and because of the purity of the S-RNA preparations achieved so far. Ingram and Pierce (l), McCully and Cantoni (2), and Bell, Tomlinson, and Tener (3) h...
متن کاملSpecies Specificity of Amino Acid Acceptor Ribonucleic Acid and Aminoacyl Soluble Ribonucleic Acid Synthetases.
Several investigators have reported that the activation of amino acids for protein synthesis, i.e. the incorporation of amino acids into soluble ribonucleic acids, is dependent upon the source of both the aminoacyl S-RNA’ synthetases and the S-RNA itself. For example, Rendi and Ochoa (1) reported that aminoacyl S-RNA synthetases from Escherichia coli could not incorporate leucine into yeast or ...
متن کاملEffect of chemical modification of dihydrouridine in yeast transfer ribonucleic acid on amino acid acceptor activity and ribosomal binding.
Dihydrouridine residues in bakers’ yeast transfer RNA were reductively cleaved with sodium borohydride. The amino acid acceptor activity of three species of transfer RNA and the ribosoma binding of one species of transfer RNA were determined for these modified transfer RNAs. The data indicate that the reductive cleavage of the dihydrouridine residues in these transfer RNAs has no effect upon th...
