Abstract
The interactions of yeast tRNATyr, spin-labelled at position i6A-37 next to the anticodon, with EF-Tu . GTP and with Escherichia coli tRNAVal (which has a complementary anticodon) have been studied. The immobilization of the spin label upon ternary complex formation shows a conformational change of the anticodon region, although this part of tRNATyr is not in direct contact with the protein, as indicated by RNase T1 digestion. Upon anticodon-anticodon interaction, no conformational change of the anticodon loop of tRNATyr was observed.
