The ternary complex (Met-tRNAi:eIF2:GTP) binds to the complex formed by the 40S subunit, eIF3 and eIF1A, to form the 43S complex. eIF1A promotes binding of the ternary complex to the 40S subunit within 43S. The initiator methionyl-tRNA from the ternary complex is positioned at the ribosomal P site.
