CC -!- FUNCTION: Catalyzes the formation of N(4)-acetylcytidine (ac(4)C) at
CC the wobble position of tRNA(Met), by using acetyl-CoA as an acetyl
CC donor and ATP (or GTP). {ECO:0000256|HAMAP-Rule:MF_01886}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=acetyl-CoA + ATP + cytidine(34) in elongator tRNA(Met) + H2O =
CC ADP + CoA + H(+) + N(4)-acetylcytidine(34) in elongator tRNA(Met) +
CC phosphate; Xref=Rhea:RHEA:43788, Rhea:RHEA-COMP:10693, Rhea:RHEA-

CC EC=2.3.1.193; Evidence={ECO:0000256|HAMAP-Rule:MF_01886};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_01886}.
CC Nucleus, nucleolus {ECO:0000256|ARBA:ARBA00004604}.
CC -!- SIMILARITY: Belongs to the TmcA family. {ECO:0000256|HAMAP-
CC Rule:MF_01886}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_01886}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
