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)-
