CC   -!- FUNCTION: Specifically acetylates 'Lys-40' in alpha-tubulin on the
CC       lumenal side of microtubules. Promotes microtubule destabilization and
CC       accelerates microtubule dynamics; this activity may be independent of
CC       acetylation activity. Acetylates alpha-tubulin with a slow enzymatic
CC       rate, due to a catalytic site that is not optimized for acetyl
CC       transfer. Enters the microtubule through each end and diffuses quickly
CC       throughout the lumen of microtubules. Acetylates only long/old
CC       microtubules because of its slow acetylation rate since it does not
CC       have time to act on dynamically unstable microtubules before the enzyme
CC       is released. {ECO:0000255|HAMAP-Rule:MF_03130}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=acetyl-CoA + L-lysyl-[alpha-tubulin] = CoA + H(+) + N(6)-
CC         acetyl-L-lysyl-[alpha-tubulin]; Xref=Rhea:RHEA:15277, Rhea:RHEA-

CC   -!- SIMILARITY: Belongs to the acetyltransferase ATAT1 family.
