RT "Complete sequence of chromosome of Exiguobacterium sibiricum 255-15.";
RL Submitted (APR-2008) to the EMBL/GenBank/DDBJ databases.
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 Evidence={ECO:0000255|HAMAP-Rule:MF_01539};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01539}.
CC -!- SIMILARITY: Belongs to the TmcAL family. {ECO:0000255|HAMAP-
CC Rule:MF_01539}.
