protein-N-terminal amino-acid acetyltransferase activity tubulin N-terminal-methionine acetyltransferase activity https://github.com/geneontology/go-ontology/issues/27532 Catalysis of the reaction: acetyl-CoA + N-terminal L-methionyl-[tubulin] = CoA + H+ + N-terminal N(alpha)-acetyl-L-methionyl-[tubulin]. The N-terminus of both alpha- and beta-tubulin are acetylated. sjm molecular_function RHEA:69607 KEGG_REACTION:R12978 GO:0120519 EC:2.3.1.308 tubulin N-terminal N-acetyltransferase activity 2024-07-10T12:20:19Z MetaCyc:RXN-22633
