CC -!- FUNCTION: Function in general translation initiation by promoting the
CC binding of the formylmethionine-tRNA to ribosomes. Seems to function
CC along with eIF-2. {ECO:0000256|ARBA:ARBA00024852, ECO:0000256|HAMAP-
CC Rule:MF_00100, ECO:0000256|RuleBase:RU000644}.
CC -!- SIMILARITY: Belongs to the TRAFAC class translation factor GTPase
CC superfamily. Classic translation factor GTPase family. IF-2 subfamily.
