Comments [?]

Function Catalyzes the formation of N(4)-acetylcytidine (ac(4)C) at the wobble position of tRNA(Met), by using acetyl-CoA as an acetyl donor and ATP (or GTP).
Catalytic activity RHEA:43788: acetyl-CoA + ATP + cytidine(34) in elongator tRNA(Met) + H2O = ADP + CoA + H(+) + N(4)-acetylcytidine(34) in elongator tRNA(Met) + phosphate
EC 2.3.1.193
Subcellular location Cytoplasm.
Similarity Belongs to the TmcA family.
