Lysine acetylation 
ε-amino group of a specific lysine of α-tubulin
Microtubules are stabilized against breakage (centrioles, basal bodies, & primary cilia)

Detyrosylation 
tyrosine can be removed by a carboxypeptidase, where it sequentially removes the C-terminal tyrosines from α-tubulin subunits.

Detyrosylated microtubules are more stable, because they are more resistant to depolymerization by kinesin-13 and related proteins.

#Unit 2. Cellular Organization

Polyglutamylation and polyglycylation are likely mutually exclusive, so they would not normally occur at the same time & both can enhance microtubule stability,

Kinesin-1 associates preferentially with detyrosylated and acetylated microtubules.
