    71929   Alpha Tubulin Acetylation  The Addition of an Acetyl Group to the Lysine 40 Residue of Alpha Tubulin. 
    5874   Microtubule  Any of the Long Generally Straight Hollow Tubes of Internal Diameter 12 15 Nm and External Diameter 24 Nm Found in a Wide Variety of Eukaryotic Cells; Each Consists (usually) of 13 Protofilaments of Polymeric Tubulin Staggered in Such a Manner That the Tubulin Monomers Are Arranged in a Helical Pattern On the Microtubular Surface and with the Alpha/beta Axes of the Tubulin Subunits Parallel to the Long Axis of the Tubule; Exist in Equilibrium with Pool of Tubulin Monomers and Can Be Rapidly Assembled or Disassembled in Response to Physiological Stimuli; Concerned with Force Generation E.g. in the Spindle. 
    19799   Tubulin N Acetyltransferase Activity  Catalysis of the Reaction: Acetyl Coa + (alpha Tubulin) L Lysine = Coa + (alpha Tubulin) N6 Acetyl L Lysine.
