Recognition of γ-Subunit by β-Subunit in Translation Initiation Factor 2. Stabilization of the GTP-Bound State of I/F 2 in Archaea and Eukaryotes

Eukaryotic and archaeal translation initiation factor 2 (e/aIF2) functions as a heterotrimeric complex. It consists of three subunits (α, β, γ). α- and β-subunits are bound to γ-subunit by hydrogen bonds and van der Waals interactions, but do not contact each other. Although main functions of the fa...
