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}.
