EC 3.4.17.24     
Accepted name: tubulin-glutamate carboxypeptidase
Reaction: 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 α- and γ-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 β-tubulin and detyrosinated α-tubulin (from which the C-terminal L-tyrosine has been removed by EC 3.4.17.17, tubulinyl-Tyr carboxypeptidase). The latter is cleaved to δ2-tubulin and further to δ3-tubulin.
Other name(s): cytosolic carboxypeptidase 1; cytosolic carboxypeptidase 5; CCP1; CCP5; Agtpbp1 (gene name); AGBL5 (gene name)
