RT "Proteogenomic analyses indicate bacterial methylotrophy and archaeal
RT heterotrophy are prevalent below the grass root zone.";
RL PeerJ 4:E2687-E2687(2016).
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.
CC {ECO:0000256|ARBA:ARBA00007733, ECO:0000256|HAMAP-Rule:MF_00100,
CC ECO:0000256|RuleBase:RU000644}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:OLD01423.1}.
