Thus, the major tyrosine identity determinants were searched by the in vitro approach using unmodified transcripts produced by T7 RNA polymerase. On the basis of the tyrosylation efficiency of tRNA variants, the strongest determinants are base pair C1-G72 and discriminator residue A73 (the 5'-phosphoryl group on C1, however, is unimportant for tyrosylation). The three anticodon bases G34, U35, and A36 contribute also to the tyrosine identity, but to a lesser extent, with G34 having the most pronounced effect. Mutation of the GUA tyrosine anticodon into a CAU methionine anticodon, however, leads to a loss of tyrosylation efficiency similar to that obtained after mutation of the C1-G72 or A73 determinants. Transplantation of the six determinants into four different tRNA frameworks and activity assays on heterologous Escherichia coli and Methanococcus jannaschii tRNA(Tyr) confirmed the completeness of the tyrosine set and the eukaryotic character of the C1-G72 base pair. On the other hand, it was found that tyrosine identity in yeast does not rely on fine architectural features of the tRNA, in particular the size and sequence of the D-loop. Noticeable, yeast TyrRS efficiently charges a variant of E. coli tRNA(Tyr) with a large extra-region provided its G1-C72 base pair is changed to a C1-G72 base pair. Finally, tyrosylation activity is compatible with a +1 shift of the anticodon in the 3'-direction but is strongly inhibited if this shift occurs in the opposite 5'-direction."xsd:string |
