carboxypeptidase B

(1) The term recommended by the IUBMB for the enzyme EC 3.4.17.2, which catalyses preferential release of C-terminal lysine or arginine.

In the plasma compartment, this family of enzymes is represented by carboxypeptidase N (CPN, [3] EC 3.4.17.3; also known as lysine carboxypeptidase, kininase I, anaphylatoxin inactivator, or plasma carboxypeptidase B) and the more recently identified carboxypeptidase U (CPU; EC 3.4.17.20; also known as carboxypeptidase R, plasma carboxypeptidase B, or TAFIa).
They cloned the CPU cDNA from human liver and deduced the amino acid sequence of the proenzyme, designating it plasma carboxypeptidase B because the active enzyme very much behaves like pancreatic carboxypeptidase B in terms of enzyme activity (7, 8).
