CC   -!- FUNCTION: Catalyzes the formation of N(4)-acetylcytidine (ac(4)C) at
CC       the wobble position of elongator tRNA(Met), using acetate and ATP as
CC       substrates. First activates an acetate ion to form acetyladenylate (Ac-
CC       AMP) and then transfers the acetyl group to tRNA to form ac(4)C34.
CC       {ECO:0000255|HAMAP-Rule:MF_01539}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=acetate + ATP + cytidine(34) in elongator tRNA(Met) = AMP +
CC         diphosphate + N(4)-acetylcytidine(34) in elongator tRNA(Met);

CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01539}.
CC   -!- SIMILARITY: Belongs to the TmcAL family. {ECO:0000255|HAMAP-
