Abstract
The functional properties of preparations of protein synthesis initiation factor eIF-2 which lack the β-subunit (as confirmed immunologically) were compared with those of the heterotrimeric factor. The former can bind guanine nucleotides but not initiator tRNA, and also exhibits a substantially reduced rate of initiation factor eIF-2B-mediated GDP/GTP-exchange.
