'''Alpha-tubulin N-acetyltransferase''' (TAT) catalyzes the conversion of acetyl-CoA and tubulin-L-lysine to CoA and tubulin-N-acetyl-L-lysine. TAT acetylates Lys40 in tubulin and is required for normal sperm flagellar function. This posttranslational modification of tubulin is conserved in long-lived microtubules. TAT can acetylate itself and this acts as a regulatory mechanism for its action on tubulin.<ref>PMID:23071314</ref> | '''Alpha-tubulin N-acetyltransferase''' (TAT) catalyzes the conversion of acetyl-CoA and tubulin-L-lysine to CoA and tubulin-N-acetyl-L-lysine.
