RT   aerobic obligate ammonia-oxidizing sulfur purple bacterium.";
RL   Submitted (APR-2010) to the EMBL/GenBank/DDBJ databases.
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:0000255|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-
