CC -!- FUNCTION: Exhibits a very high intrinsic GTPase hydrolysis rate.
CC Involved in the addition of a carboxymethylaminomethyl (cmnm) group at
CC the wobble position (U34) of certain tRNAs, forming tRNA-
CC cmnm(5)s(2)U34. {ECO:0000256|HAMAP-Rule:MF_00379}.
CC -!- COFACTOR:
CC Name=K(+); Xref=ChEBI:CHEBI:29103;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00379};
CC Note=Binds 1 potassium ion per subunit. {ECO:0000256|HAMAP-
CC Rule:MF_00379};
CC -!- SUBUNIT: Homodimer. Heterotetramer of two MnmE and two MnmG subunits.
CC {ECO:0000256|HAMAP-Rule:MF_00379}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00379}.
CC -!- SIMILARITY: Belongs to the TRAFAC class TrmE-Era-EngA-EngB-Septin-like
CC GTPase superfamily. TrmE GTPase family. {ECO:0000256|ARBA:ARBA00011043,
CC ECO:0000256|HAMAP-Rule:MF_00379, ECO:0000256|RuleBase:RU003313}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_00379}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
