General annotation (Comments)

Function

Exhibits a very high intrinsic GTPase hydrolysis rate. Involved in the addition of a carboxymethylaminomethyl (cmnm) group at the wobble position (U34) of certain tRNAs, forming tRNA-cmnm5s2U34 By similarity. HAMAP-Rule MF_00379

Cofactor

Binds 1 potassium ion per subunit By similarity.

Subunit structure

Homodimer By similarity. Heterotetramer of two MnmE and two MnmG subunits By similarity.

Subcellular location

Cytoplasm By similarity.

Sequence similarities

Belongs to the Era/MnmE GTP-binding protein family. MnmE subfamily.

Contains 1 G (guanine nucleotide-binding) domain.
