>gnl|CDD|199850 cd03868, M14_CPD_I, Peptidase M14 carboxypeptidase subfamily
N/E-like; Carboxypeptidase D, domain I subgroup. The
first carboxypeptidase (CP)-like domain of
Carboxypeptidase D (CPD; EC 3.4.17.22), domain I. CPD
differs from all other metallocarboxypeptidases in that
it contains multiple CP-like domains. CPD belongs to the
N/E-like subfamily of the M14 family of
metallocarboxypeptidases (MCPs).The M14 family are
zinc-binding CPs which hydrolyze single, C-terminal
amino acids from polypeptide chains, and have a
recognition site for the free C-terminal carboxyl group,
which is a key determinant of specificity. CPD is a
single-chain protein containing a signal peptide, three
tandem repeats of CP-like domains separated by short
bridge regions, followed by a transmembrane domain, and
a C-terminal cytosolic tail. The first two CP-like
domains of CPD contain all of the essential active site
and substrate-binding residues, the third CP-like domain
lacks critical residues necessary for enzymatic activity
and is inactive towards standard CP substrates. Domain I
is optimally active at pH 6.3-7.5 and prefers substrates
with C-terminal Arg, whereas domain II is active at pH
5.0-6.5 and prefers substrates with C-terminal Lys. This
Domain I family contains two contiguous surface
cysteines that may become palmitoylated and target the
enzyme to membranes, thus regulating intracellular
trafficking. CPD functions in the processing of proteins
that transit the secretory pathway, and is present in
all vertebrates as well as Drosophila. It is broadly
distributed in all tissue types. Within cells, CPD is
present in the trans Golgi network and immature
secretory vesicles, but is excluded from mature
vesicles. It is thought to play a role in the processing
of proteins that are initially processed by furin or
related endopeptidases present in the trans Golgi
network, such as growth factors and receptors. CPD is
implicated in the pathogenesis of lupus erythematosus
(LE), it is regulated by TGF-beta in various cell types
of murine and human origin and is significantly
down-regulated in CD14 positive cells isolated from
patients with LE. As down-regulation of CPD leads to
down-modulation of TGF-beta, CPD may have a role in a
positive feedback loop. In D. melanogaster, the CPD
variant 1B short (DmCPD1Bs) is necessary and sufficient
for viability of the fruit fly.

>gnl|CDD|199842 cd03858, M14_CP_N-E_like, Peptidase M14 carboxypeptidase subfamily
N/E-like. Carboxypeptidase (CP) N/E-like subfamily of
the M14 family of metallocarboxypeptidases (MCPs). The
M14 family are zinc-binding CPs which hydrolyze single,
C-terminal amino acids from polypeptide chains, and have
a recognition site for the free C-terminal carboxyl
group, which is a key determinant of specificity. The
N/E subfamily includes eight members, of which five
(CPN, CPE, CPM, CPD, CPZ) are considered enzymatically
active, while the other three are non-active (CPX1,
PCX2, ACLP/AEBP1) and lack the critical active site and
substrate-binding residues considered necessary for CP
activity. These non-active members may function as
binding proteins or display catalytic activity towards
other substrates. Unlike the A/B CP subfamily, enzymes
belonging to the N/E subfamily are not produced as
inactive precursors that require proteolysis to produce
the active form; rather, they rely on their substrate
specificity and subcellular compartmentalization to
prevent inappropriate cleavages that would otherwise
damage the cell. In addition, all members of the N/E
subfamily contain an extra C-terminal domain that is not
present in the A/B subfamily. This domain has structural
homology to transthyretin and other proteins and has
been proposed to function as a folding domain. The
active N/E enzymes fulfill a variety of cellular
functions, including prohormone processing, regulation
of peptide hormone activity, alteration of
protein-protein or protein-cell interactions and
transcriptional regulation.

>gnl|CDD|199843 cd03859, M14_CPT, Peptidase M14 Carboxypeptidase T subfamily.
Peptidase M14-like domain of carboxypeptidase (CP) T
(CPT), CPT belongs to the M14 family of
metallocarboxypeptidases (MCPs). The M14 family are
zinc-binding CPs which hydrolyze single, C-terminal
amino acids from polypeptide chains, and have a
recognition site for the free C-terminal carboxyl group,
which is a key determinant of specificity. CPT has
moderate similarity to CPA and CPB, and exhibits
dual-substrate specificity by cleaving C-terminal
hydrophobic amino acid residues like CPA and C-terminal
positively charged residues like CPB. CPA and CPB are
M14 family peptidases but do not belong to this CPT
group. The substrate specificity difference between CPT
and CPA and CPB is ascribed to a few amino acid
substitutions at the substrate-binding pocket while the
spatial organization of the binding site remains the
same as in all Zn-CPs. CPT has increased thermal
stability in presence of Ca2+ ions, and two disulfide
bridges which give an additional stabilization factor.

>gnl|CDD|199875 cd06905, M14-like_8, Peptidase M14-like domain; uncharacterized
subfamily. A functionally uncharacterized subgroup of
the M14 family of metallocarboxypeptidases (MCPs). The
M14 family are zinc-binding carboxypeptidases (CPs)
which hydrolyze single, C-terminal amino acids from
polypeptide chains, and have a recognition site for the
free C-terminal carboxyl group, which is a key
determinant of specificity. Two major subfamilies of the
M14 family, defined based on sequence and structural
homology, are the A/B and N/E subfamilies. Enzymes
belonging to the A/B subfamily are normally synthesized
as inactive precursors containing preceding signal
peptide, followed by an N-terminal pro-region linked to
the enzyme; these proenzymes are called
procarboxypeptidases. The A/B enzymes can be further
divided based on their substrate specificity;
Carboxypeptidase A-like (CPA-like) enzymes favor
hydrophobic residues while carboxypeptidase B-like
(CPB-like) enzymes only cleave the basic residues lysine
or arginine. The A forms have slightly different
specificities, with Carboxypeptidase A1 (CPA1)
preferring aliphatic and small aromatic residues, and
CPA2 preferring the bulky aromatic side chains. Enzymes
belonging to the N/E subfamily enzymes are not produced
as inactive precursors and instead rely on their
substrate specificity and subcellular
compartmentalization to prevent inappropriate cleavages.
They contain an extra C-terminal transthyretin-like
domain, thought to be involved in folding or formation
of oligomers. MCPs can also be classified based on
their involvement in specific physiological processes;
the pancreatic MCPs participate only in alimentary
digestion and include carboxypeptidase A and B (A/B
subfamily), while others, namely regulatory MCPs or the
N/E subfamily, are involved in more selective reactions,
mainly in non-digestive tissues and fluids, acting on
blood coagulation/fibrinolysis, inflammation and local
anaphylaxis, pro-hormone and neuropeptide processing,
cellular response and others. Another MCP subfamily,
is that of succinylglutamate desuccinylase
/aspartoacylase, which hydrolyzes N-acetyl-L-aspartate
(NAA), and deficiency in which is the established cause
of Canavan disease. Another subfamily (referred to as
subfamily C) includes an exceptional type of activity in
the MCP family, that of dipeptidyl-peptidase activity of
gamma-glutamyl-(L)-meso-diaminopimelate peptidase I
which is involved in bacterial cell wall metabolism.

>gnl|CDD|199848 cd03866, M14_CPM, Peptidase M14 carboxypeptidase subfamily
N/E-like; Carboxypeptidase M subgroup. Peptidase M14
Carboxypeptidase (CP) M (CPM) belongs to the N/E
subfamily of the M14 family of metallocarboxypeptidases
(MCPs).The M14 family are zinc-binding CPs which
hydrolyze single, C-terminal amino acids from
polypeptide chains, and have a recognition site for the
free C-terminal carboxyl group, which is a key
determinant of specificity. CPM is an extracellular
glycoprotein, bound to cell membranes via a
glycosyl-phosphatidylinositol on the C-terminus of the
protein. It specifically removes C-terminal basic
residues such as lysine and arginine from peptides and
proteins. The highest levels of CPM have been found in
human lung and placenta, but significant amounts are
present in kidney, blood vessels, intestine, brain, and
peripheral nerves. CPM has also been found in soluble
form in various body fluids, including amniotic fluid,
seminal plasma and urine. Due to its wide distribution
in a variety of tissues, it is believed that it plays an
important role in the control of peptide hormones and
growth factor activity on the cell surface and in the
membrane-localized degradation of extracellular
proteins, for example it hydrolyses the C-terminal
arginine of epidermal growth factor (EGF) resulting in
des-Arg-EGF which binds to the EGF receptor (EGFR) with
an equal or greater affinity than native EGF. CPM is a
required processing enzyme that generates specific
agonists for the B1 receptor.

>gnl|CDD|199844 cd03860, M14_CP_A-B_like, Peptidase M14 carboxypeptidase subfamily
A/B-like. The Peptidase M14 Carboxypeptidase (CP) A/B
subfamily is one of two main M14 CP subfamilies defined
by sequence and structural homology, the other being the
N/E subfamily. CPs hydrolyze single, C-terminal amino
acids from polypeptide chains. They have a recognition
site for the free C-terminal carboxyl group, which is a
key determinant of specificity. Enzymes belonging to the
A/B subfamily are normally synthesized as inactive
precursors containing preceding signal peptide, followed
by a globular N-terminal pro-region linked to the
enzyme; these proenzymes are called
procarboxypeptidases. The A/B enzymes can be further
divided based on their substrate specificity;
Carboxypeptidase A-like (CPA-like) enzymes favor
hydrophobic residues while carboxypeptidase B-like
(CPB-like) enzymes only cleave the basic residues lysine
or arginine. There are nine members in the A/B family:
CPA1, CPA2, CPA3, CPA4, CPA5, CPA6, CPB, CPO and CPU.
CPA1, CPA2 and CPB are produced by the pancreas. The A
forms have slightly different specificities, with CPA1
preferring aliphatic and small aromatic residues, and
CPA2 preferring the bulkier aromatic side chains. CPA3
is found in secretory granules of mast cells and
functions in inflammatory processes. CPA4 is detected in
hormone-regulated tissues, and is thought to play a role
in prostate cancer. CPA5 is present in discrete regions
of pituitary and other tissues, and cleaves aliphatic
C-terminal residues. CPA6 is highly expressed in
embryonic brain and optic muscle, suggesting that it may
play a specific role in cell migration and axonal
guidance. CPU (also called CPB2) is produced and
secreted by the liver as the inactive precursor, PCPU,
commonly referred to as thrombin-activatable
fibrinolysis inhibitor (TAFI). Little is known about CPO
but it has been suggested to have specificity for acidic
residues.

N/E-like; Carboxypeptidase N subgroup. Peptidase M14
Carboxypeptidase N (CPN, also known as kininase I,
creatine kinase conversion factor, plasma
carboxypeptidase B, arginine carboxypeptidase, and
protaminase; EC 3.4.17.3) is an extracellular
glycoprotein synthesized in the liver and released into
the blood, where it is present in high concentrations.
CPN belongs to the N/E subfamily of the M14 family of
metallocarboxypeptidases (MCPs).The M14 family are
zinc-binding carboxypeptidases (CPs) which hydrolyze
single, C-terminal amino acids from polypeptide chains,
and have a recognition site for the free C-terminal
carboxyl group, which is a key determinant of
specificity. CPN plays an important role in protecting
the body from excessive buildup of potentially
deleterious peptides that normally act as local
autocrine or paracrine hormones. It specifically removes
C-terminal basic residues. As CPN can cleave lysine more
avidly than arginine residues it is also called lysine
carboxypeptidase. CPN substrates include peptides found
in the bloodstream, such as kinins (e.g. bradykinin,
kalinin, met-lys-bradykinin), complement anaphylatoxins
and creatine kinase MM (CK-MM). By removing just one
amino acid, CPN can alter peptide activity and receptor
binding. For example Bradykinin, a nine-residue peptide
released from kiningen in response to tissue injury
which is inactivated by CPN, anaphylatoxins which are
regulated by CPN by the cleaving and removal of their
C-terminal arginines resulting in a reduction in their
biological activities of 10-100-fold, and creatine
kinase MM, a cytosolic enzyme that catalyzes the
reversible transfer of a phosphate group from ATP to
creatine, and is regulated by CPN by the cleavage of
C-terminal lysines. Like the other N/E subfamily
members, two surface loops surrounding the active-site
groove restrict access to the catalytic center, thus
restricting larger protein carboxypeptidase inhibitors
from inhibiting CPN.

Carboxypeptidase (CP) E (CPE, also known as
carboxypeptidase H, and enkephalin convertase; EC
3.4.17.10) belongs to the N/E subfamily of the M14
family of metallocarboxypeptidases (MCPs).The M14 family
are zinc-binding CPs which hydrolyze single, C-terminal
amino acids from polypeptide chains, and have a
recognition site for the free C-terminal carboxyl group,

important enzyme responsible for the proteolytic
processing of prohormone intermediates (such as
pro-insulin, pro-opiomelanocortin, or
pro-gonadotropin-releasing hormone) by specifically
removing C-terminal basic residues. In addition, it has
been proposed that the regulated secretory pathway (RSP)
of the nervous and endocrine systems utilizes
membrane-bound CPE as a sorting receptor. A naturally
occurring point mutation in CPE reduces the stability of
the enzyme and causes its degradation, leading to an
accumulation of numerous neuroendocrine peptides that
result in obesity and hyperglycemia. Reduced CPE enzyme
and receptor activity could underlie abnormal placental
phenotypes from the observation that CPE is
down-regulated in enlarged placentas of interspecific
hybrid (interspecies hybrid placental dysplasia, IHPD)
and cloned mice.

N/E-like; Carboxypeptidase X subgroup. Peptidase
M14-like domain of carboxypeptidase (CP)-like protein X
(CPX), CPX forms a distinct subgroup of the N/E
subfamily of the M14 family of metallocarboxypeptidases
(MCPs). The M14 family are zinc-binding CPs which
hydrolyze single, C-terminal amino acids from
polypeptide chains, and have a recognition site for the
free C-terminal carboxyl group, which is a key
determinant of specificity. Proteins belonging to this
subgroup include CP-like protein X1 (CPX1), CP-like
protein X2 (CPX2), and aortic CP-like protein (ACLP)
and its isoform adipocyte enhancer binding protein-1
(AEBP1). AEBP1 is a truncated form of ACLP, which may
arise from alternative splicing of the gene. These
proteins are inactive towards standard CP substrates
because they lack one or more critical active site and
substrate-binding residues that are necessary for
activity. They may function as binding proteins rather
than as active CPs or display catalytic activity toward
other substrates. Proteins in this subgroup also
contain an N-terminal discoidin domain. The CP domain is
important for the function of AEBP1 as a transcriptional
repressor. AEBP1 is involved in several biological
processes including adipogenesis, macrophage cholesterol
homeostasis, and inflammation. In macrophages, AEBP1
promotes the expression of IL-6, TNF-alpha, MCP-1, and
iNOS whose expression is tightly regulated by NF-kappaB
activity. ACLP, a secreted protein that associates with
the extracellular matrix, is essential for abdominal
wall development and contributes to dermal wound
healing.

>gnl|CDD|199869 cd06248, M14_CP_A-B_like_1, Peptidase M14 carboxypeptidase
subfamily A/B-like; uncharacterized subgroup. The
Peptidase M14 Carboxypeptidase A/B-like subfamily is one
of two main M14 carboxypeptidase subfamilies, defined by
sequence and structural homology, the other being N/E.
Carboxypeptidases (CPs) hydrolyze single, C-terminal
amino acids from polypeptide chains. They have a
recognition site for the free C-terminal carboxyl group,
which is a key determinant of specificity. Majority of
the proteins in this subfamily have not been
characterized as yet. The A/B enzymes are normally
synthesized as inactive precursors containing preceding
signal peptide, followed by a globular N-terminal
pro-region linked to the enzyme; the proenzymes are
called procarboxypeptidases. These enzymes exhibit
distinct substrate specificity pattern; Carboxypeptidase
A-like (CPA-like) enzymes favor hydrophobic residues
while carboxypeptidase B-like (CPB-like) enzymes only
cleave the basic residues lysine or arginine. There are
nine members in the A/B family: CPA1, CPA2, CPA3, CPA4,
CPA5, CPA6, CPB, CPO and CPU. CPA1, CPA2 and CPB are
produced by the pancreas. The A forms have slightly
different specificities, with CPA1 preferring aliphatic
and small aromatic residues, and CPA2 preferring the
bulkier aromatic side chains. CPA3 is found in secretory
granules of mast cells and functions in inflammatory
processes. CPA4, detected in hormone-regulated tissues,
is thought to play a role in prostate cancer. CPA5 is
present in discrete regions of pituitary and other
tissues, and cleaves aliphatic C-terminal residues. CPA6
is highly expressed in embryonic brain and optic muscle,
suggesting that it may play a specific role in cell
migration and axonal guidance. CPU (also called CPB2) is
produced and secreted by the liver as the inactive
precursor PCPU, commonly referred to as
thrombin-activatable fibrinolysis inhibitor (TAFI).
Little is known about CPO but it has been suggested to
have specificity for acidic residues.

is that of succinylglutamate desuccinylase

A/B-like; Carboxypeptidase A6 subgroup.
Carboxypeptidase (CP) A6 (CPA6, also known as CPAH; EC
3.4.17.1), belongs to the carboxypeptidase A/B
subfamily of the M14 family of metallocarboxypeptidases
(MCPs). The M14 family are zinc-binding CPs which
hydrolyze single, C-terminal amino acids from
polypeptide chains, and have a recognition site for the
free C-terminal carboxyl group, which is a key
determinant of specificity. CPA6 prefers large
hydrophobic C-terminal amino acids as well as
histidine, while peptides with a penultimate glycine or
proline are very poorly cleaved. Several neuropeptides
are processed by CPA6, including Met- and
Leu-enkephalin, angiotensin I, and neurotensin. CPA6
converts enkephalin and neurotensin into forms known to
be inactive toward their receptors, but converts
inactive angiotensin I into the biologically active
angiotensin II. Thus, CPA6 plays a possible role in the
regulation of neuropeptides in the extracellular
environment within the olfactory bulb where it is
highly expressed. It is also broadly expressed in
embryonic tissue, being found in neuronal tissues,
bone, skin as well as the lateral rectus eye muscle. A
disruption in the CPA6 gene is linked to Duane
syndrome, a defect in the abducens nerve/lateral rectus
muscle connection.

>gnl|CDD|133105 cd06247, M14_CPO, Peptidase M14 carboxypeptidase subfamily
A/B-like; Carboxypeptidase O subgroup. Peptidase M14
carboxypeptidase (CP) O (CPO, also known as
metallocarboxypeptidase C; EC 3.4.17.) belongs to the
carboxypeptidase A/B subfamily of the M14 family of
metallocarboxypeptidases (MCPs). The M14 family are
zinc-binding CPs which hydrolyze single, C-terminal
amino acids from polypeptide chains, and have a
recognition site for the free C-terminal carboxyl
group, which is a key determinant of specificity. CPO
has not been well characterized as yet, and little is
known about it. Based on modeling studies, CPO has been
suggested to have specificity for acidic residues
rather than aliphatic/aromatic residues as in A-like
enzymes or basic residues as in B-like enzymes. It
remains to be demonstrated that CPO is functional as an
MCP.
