DE   [beta-tubulin]-L-lysine N-acetyltransferase.
CA   L-lysyl-[beta-tubulin] + acetyl-CoA = N(6)-acetyl-L-lysyl-[beta-tubulin]
CA   + CoA + H(+).
CC   -!- The enzyme acetylates L-lysine at position 252 of beta-tubulin, which
CC       is located at the interface of alpha/beta-tubulin heterodimers and
CC       interacts with the phosphate group of the alpha-tubulin-bound GTP.
CC   -!- The acetylation is thought to attenuate tubulin incorporation into
CC       microtubules.
CC   -!- The enzyme catalyzing this activity (NAA50) also catalyzes the
CC       acetylation of certain N-terminal methionyl residues. That activity
CC       is classified as EC 2.3.1.258. cf. EC 2.3.1.108.
