CC   -!- FUNCTION: One of the essential components for the initiation of protein
CC       synthesis. Protects formylmethionyl-tRNA from spontaneous hydrolysis
CC       and promotes its binding to the 30S ribosomal subunits. Also involved
CC       in the hydrolysis of GTP during the formation of the 70S ribosomal
CC       complex. {ECO:0000255|HAMAP-Rule:MF_00100}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {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}.
