[elongator tRNAMet]-cytidine34 + ATP + acetyl-CoA
tRNAMet cytidine acetyltransferase acetylates the wobble base C34 of the elongation-specific tRNAMet. TmcA specifically recognizes the anticodon stem of tRNAMet, thus distinguishing between tRNAMet and tRNAIle2, which is structurally similar and has the same anticodon loop

[elongator tRNAMet]-cytidine34 + ATP + acetyl-CoA
ATP/GTP hydrolysis by TmcA is stimulated in the presence of acetyl-CoA and tRNAMet. TmcA hydrolyses ATP or GTP between the beta- and gamma-phosphates, as shown by the detection of labelled ADP (or GDP). A mutation study reveals that Escherichia coli TmcA strictly discriminates elongator tRNAMet from the structurally similar tRNAIle by mainly recognizing the C27ÂG43 pair in the anticodon stem
