DE   tRNA(Met) cytidine acetyltransferase.
CA   cytidine(34) in elongator tRNA(Met) + acetyl-CoA + ATP + H2O = N(4)-
CA   acetylcytidine(34) in elongator tRNA(Met) + ADP + phosphate + CoA + H(+).
CC   -!- The enzyme acetylates the wobble base C34 of the CAU anticodon of
CC       elongation-specific tRNA(Met).
CC   -!- Escherichia coli TmcA strictly discriminates elongator tRNA(Met) from
CC       tRNA(Ile), which is structurally similar and has the same anticodon
CC       loop, mainly by recognizing the C27-G43 pair in the anticodon stem.
CC   -!- The enzyme can use GTP in place of ATP for formation of N(4)-
CC       acetylcytidine.
