    ..Because the alpha subunit markedly reinforces the affinity of tRNA for the gamma subunit, a contribution of the alpha subunit to the switch movements observed in the gamma structure is considered. ..

    ..We conclude that despite considerable structural homology between the core ? subunit of aIF2 and the elongation factor EF1A, these two G proteins of the translation apparatus use very different tRNA-binding strategies...

    ..The nucleotide state of aIF2 shown here is indicative of a similar mechanism in archaea. Finally, we consider the possibility that release of Pi takes place after e/aIF2gamma has been informed of e/aIF1 dissociation by e/aIF2beta...
