pubmed:abstractText |
The complexes of N-AcPhe-tRNAPhe (or non-aminoacylated tRNAPhe) from yeast with 70S ribosomes from E. coli have been studied fluorimetrically utilizing wybutine, the fluorophore naturally occurring next to the 3' side of the anticodon, as a probe for conformational changes of the anticodon loop. The fluorescence parameters are very similar for tRNA bound to both ribosomal sites, thus excluding an appreciable conformational change of the anticodon loop upon translocation. The spectral change observed upon binding of tRNAPhe to the P site even in the absence of poly(U) is similar to the one brought about by binding of poly(U) alone to the tRNA. This effect may be due to a hydrophobic binding site of the anticodon loop or to a conformational change of the loop induced by binding interactions of various tRNA sites including the anticodon.
