these data indicate that all of the metallocarboxypeptidases are related , but the nondigestive carboxypeptidases with more specialized functions , present in cell membranes , blood plasma , or secretory granules ( i.e. , carboxypeptidase m , carboxypeptidase n and carboxypeptidase h ) , are more closely related to each other ( 41-49 % identity ) than they are to carboxypeptidase a or b ( 15-20 % identity ) .
