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

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

Detyrosylation 

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