Notes
GTPase activity is essential for modification function. Mutants are hypomodified for s(2)U34 in tRNA(Lys). The carboxymethylaminomethyl donor is unknown. U34 is the wobble base.mnmE has proposed to be epistatic to mnmG, preceding it in the pathway (Bregeon, 2001), but Yim (2000) suggest that the MnmE and MnmG activities are interdependent, not sequential. MnmG(GidA) and MnmE form a heterotetrameric complex (Yim, 2006).[4]
