Tubulinyl-Tyr carboxypeptidase (, carboxypeptidase-tubulin, soluble carboxypeptidase, tubulin-tyrosine carboxypeptidase, tubulin carboxypeptidase, tubulinyltyrosine carboxypeptidase, tyrosinotubulin carboxypeptidase, tyrosyltubulin carboxypeptidase, TTCPase, brain I carboxypeptidase) is an enzyme. 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.
