A Conforrnational Study of Yeast Phenylalanine Transfer Ribonucleic Acid*
Yeast phenylalanine tRNA (tRNAPhe) exhibits a 4$-fold enhancement of fluorescence in response to the addition of Mg2+. Concurrently, over the same concentration range (0 to 0.4 m&r) of Mg2+, the circular dichroism peak at 263 nm displays a 20% increase in ellipticity and a blue shift of 2 nm. The existence of the negative circular dichroism band at 295 nm appears to be cation-dependent. This co...

متن کاملLarge Qligonucleotide Sequences in Wheat Germ Phenylalanine Transfer Ribonucleic Acid
The nucleotide sequence analysis of tRNA has required (a) identification of fragments isolated from complete digestion with pancreatic RNase and RNase T1 and, in addition, (b) the analysis of large oligonucleotide fragments produced by partial digestion with RNase T1 (l-4) and, in some cases, partial digestion with pancreatic RNase (5). In continuation of the work reported in the preceding pape...
متن کاملSynthesis and structure of the hypermodified nucleoside of rat liver phenylalanine transfer ribonucleic Acid.
The first synthesis of (alphaS,betaS)-beta-hydroxy-alpha-[(methoxycarbonyl)amino]-4,6-dimethyl-9-oxo-3-beta-D-ribofuranosyl-4,9-dihydro-3H-imidazo[1,2-a]purine-7-butanoic acid methyl ester [(alphaS,betaS)-11] has been achieved by OsO(4) oxidation of [S-(E)]-4-[4,6-dimethyl-9-oxo-3-[2,3,5-tris-O-(tert-butyldimethylsilyl)-beta-D-ribofuranosyl]-4,9-dihydro-3H-imidazo[1,2-a]purin-7-yl]-2-[(methoxyc...
متن کاملThree Photo-Cross-Linked Complexes of Yeast Phenylalanine Snecific Transfer Ribonucleic Acid with Aminoacvl
Yeast tRNAPhe has been cross-linked photochemically to three aminoacyl-tRNA synthetases, yeast phenylalanyltRNA synthetase, Escherichia coli isoleucyl-tRNA synthetase, and E. coli valyl-tRNA synthetase. The two non-cognate enzymes are known to interact with tRNAPhe. In each complex, three regions on the tRNA are found to cross-link. Two of these are common to all of the complexes, while the thi...
