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:0000255|HAMAP-Rule:MF_00100}.
CC -!- SIMILARITY: Belongs to the TRAFAC class translation factor GTPase
CC superfamily. Classic translation factor GTPase family. IF-2 subfamily.
CC {ECO:0000255|HAMAP-Rule:MF_00100}.
