Tubulinyl-Tyr carboxypeptidase (EC 3.4.17.17, carboxypeptidase-tubulin, soluble carboxypeptidase, tubulin-tyrosine carboxypeptidase, tubulin carboxypeptidase, tubulinyltyrosine carboxypeptidase, tyrosinotubulin carboxypeptidase, tyrosyltubulin carboxypeptidase, TTCPase, brain I carboxypeptidase) is an enzyme.[1][2][3] This enzyme catalyses the following chemical reaction

Cleavage of the -Glu--Tyr bond to release the C-terminal tyrosine residue from the native tyrosinated tubulin. Inactive on Z-Glu-Tyr

This enzyme is active at neutral pH.

This activity has been linked to proteins such as AGTPBP1 in human.[4]
