it is distinct from previously described carboxypeptidases , and appears to have specificity for tubulin as it is not inhibited by peptides and proteins with cooh-terminal tyrosine , and because , unlike carboxypeptidase a ( which by removing tyrosine from aldolase causes its inactivation ) , this enzyme does not decrease aldolase activity .
