| Cytosolic carboxypeptidase 5. |
| Reaction catalysed |

- Delta-2-[tubulin] + H(2)O <=> Delta-3-[tubulin] + L-glutamate
|
| Comment(s) |
|---|
- This is a subfamily of enzymes that cleave C-terminal and/or side
chain amino acids from tubulins.
- The dual-specificity enzymes can cleave both alpha- and gamma-linked
L-glutamate from tubulins, removing the posttranslationally added
polyglutamyl side chains from the C-terminal regions.
- In addition, the enzyme removes two glutamate residues from the
C-terminus of beta-tubulin and detyrosinated alpha-tubulin (from
which the C-terminal L-tyrosine has been removed by EC 3.4.17.17).
- The latter is cleaved to Delta-2-tubulin and further to Delta-3-
tubulin.
