CC -!- FUNCTION: RNA cytidine acetyltransferase with specificity toward both
CC 18S rRNA and tRNAs. Catalyzes the formation of N(4)-acetylcytidine
CC (ac4C) in 18S rRNA. Required for early nucleolar cleavages of precursor
CC rRNA at sites A0, A1 and A2 during 18S rRNA synthesis. Catalyzes the
CC formation of ac4C in serine and leucine tRNAs. Requires a tRNA-binding
CC adapter protein for full tRNA acetyltransferase activity but not for
CC 18S rRNA acetylation. {ECO:0000256|HAMAP-Rule:MF_03211}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a cytidine in 18S rRNA + acetyl-CoA + ATP + H2O = ADP + an
CC N(4)-acetylcytidine in 18S rRNA + CoA + H(+) + phosphate;
