Subcellular localization of cytokinins in transfer ribonucleic Acid.
Evidence on the localization of cytokinins in chloroplast tRNA was obtained by comparison of Euglena gracilis var. bacillaris light-grown and dark-grown wild type cultures and chloroplast-bleached mutant strains. The several cytokinins characteristic of tRNA were separated by Sephadex LH-20 column chromatography of the hydrolysates and were quantitatively determined by tobacco bioassays of the ...
متن کاملTransfer ribonucleic acid nucleotidyltransferase and transfer ribonucleic acid in Sendai virions.
Sendai virions contain both transfer ribonucleic acid (tRNA) nucleotidyltransferase and its substrate, tRNA missing its CCA-OH end.
متن کاملChicken liver transfer ribonucleic acid: heterologous interaction of alanine transfer ribonucleic acid with yeast.
We are attempting to determine the nature of specific RNA-protein interactions by study of tRNA charging by homologous and heterologous enzymes. tRNAklatRNARNA3 t were prepared by phenoxyacetylation of alanyl-tRNA and separation on benzoylated DEAE-cellulose (Gillam, Blew, Warrington, von Tigerstrom & Tener, 1968). A partially purified alanyl-tRNA synthetase from yeast forms alanyl-tRNAAla tand...
متن کاملAffinity chromatography of aminoacyl-transfer ribonucleic acid synthetases. Cognate transfer ribonucleic acid as a ligand.
The use of tRNA affinity columns for the purification of aminoacyl-tRNA synthetases was investigated. A purification method for valyl-tRNA synthetase from Bacillus stearothermophilus is described that uses two affinity columns, one containing the pure cognate tRNA, and the other containing all tRNA species except the cognate tRNA. A method for the rapid preparation of the two columns was develo...
متن کاملThe activation of arginyl transfer ribonucleic acid synthetase by transfer ribonucleic acid.
The arginine-activating enzyme of Escherichk coli requires transfer ribonucleic acid (tRNA) for catalysis of the ATP-pyrophosphate exchange reaction. Only the specific arginiie-accepting tRNA is effective5 and the terminal adenylic acid residue is essential for the reaction. A previously described isotope-trapping experiment led to the suggestion that an arginyl-tRNA ester was not formed during...
