>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|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|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.

M14-like domain of carboxypeptidase (CP) Z (CPZ), CPZ
belongs to the N/E subfamily of the M14 family of

zinc-binding CPs which hydrolyze single, C-terminal

recognition site for the free C-terminal carboxyl group,

secreted Zn-dependent enzyme whose biological function
is largely unknown. Unlike other members of the N/E
subfamily, CPZ has a bipartite structure, which consists
of an N-terminal cysteine-rich domain (CRD) whose
sequence is similar to Wnt-binding proteins, and a
C-terminal CP catalytic domain that removes C-terminal
Arg residues from substrates. CPZ is enriched in the
extracellular matrix and is widely distributed during
early embryogenesis. That the CRD of CPZ can bind to
Wnt4 suggests that CPZ plays a role in Wnt signaling.

>gnl|CDD|199846 cd03864, M14_CPN, Peptidase M14 carboxypeptidase subfamily
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.

N/E-like; Carboxypeptidase E subgroup. Peptidase M14
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,
which is a key determinant of specificity. CPE is an
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.

and related proteins. The M14 family of
metallocarboxypeptidases (MCPs), also known as
funnelins, 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 cleavage.
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.

is found C-terminal to the M14 carboxypeptidase (CP) N/E
subfamily containing zinc-binding enzymes that 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

active members (carboxypeptidase N, E, M, D, and Z), as
well as non-active members (carboxypeptidase-like
protein 1, -2, aortic CP-like protein, and adipocyte
enhancer binding protein-1) which lack the critical
active site and substrate-binding residues considered
necessary for activity. 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. For M14
CPs, it has been suggested that this domain may assist
in folding of the CP domain, regulate enzyme activity,
or be involved in interactions with other proteins or
with membranes; for carboxypeptidase M, it may interact
with the bradykinin 1 receptor at the cell surface. This
domain may also be found in other peptidase families.

zinc-binding CPs which hydrolyze single, C-terminal

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.

Carboxypeptidase A-like (CPA-like) enzymes favor

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.

>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.

Carboxypeptidase (CP) B2 (CPB2, also known as plasma
carboxypeptidase B, carboxypeptidase U, and CPU),
belongs to the carboxpeptidase A/B subfamily of the M14
family of metallocarboxypeptidases (MCPs). The M14

C-terminal amino acids from polypeptide chains, and have
a recognition site for the free C-terminal carboxyl

enzyme displays B-like activity; it only cleaves the
basic residues lysine or arginine. It is produced and
secreted by the liver as the inactive precursor,
procarboxypeptidase U or PCPB2, commonly referred to as
thrombin-activatable fibrinolysis inhibitor (TAFI). It
circulates in plasma as a zymogen bound to plasminogen,
and the active enzyme, TAFIa, inhibits fibrinolysis. It
is highly regulated, increased TAFI concentrations are
thought to increase the risk of thrombosis and coronary
artery disease by reducing fibrinolytic activity while
low TAFI levels have been correlated with chronic liver
disease.

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.

Catalytic domain of a functionally diverse set of
proteins, most of which are phosphatases. The conserved
catalytic core of this domain contains a His residue
which is phosphorylated in the reaction. This set of
proteins includes cofactor-dependent and
cofactor-independent phosphoglycerate mutases (dPGM, and
BPGM respectively), fructose-2,6-bisphosphatase
(F26BP)ase, Sts-1, SixA, histidine acid phosphatases,
phytases, and related proteins. Functions include roles
in metabolism, signaling, or regulation, for example
F26BPase affects glycolysis and gluconeogenesis through
controlling the concentration of F26BP; BPGM controls
the concentration of 2,3-BPG (the main allosteric
effector of hemoglobin in human blood cells); human
Sts-1 is a T-cell regulator; Escherichia coli Six A
participates in the ArcB-dependent His-to-Asp
phosphorelay signaling system; phytases scavenge
phosphate from extracellular sources. Deficiency and
mutation in many of the human members result in disease,
for example erythrocyte BPGM deficiency is a disease
associated with a decrease in the concentration of
2,3-BPG. Clinical applications include the use of
prostatic acid phosphatase (PAP) as a serum marker for
prostate cancer. Agricultural applications include the
addition of phytases to animal feed.

>gnl|CDD|240000 cd04629, CBS_pair_16, The CBS domain, named after human CBS, is a
small domain originally identified in cystathionine
beta-synthase and is subsequently found in a wide range
of different proteins. CBS domains usually occur in
tandem repeats. They associate to form a so-called
Bateman domain or a CBS pair based on crystallographic
studies in bacteria. The CBS pair was used as a basis
for this cd hierarchy since the human CBS proteins can
adopt the typical core structure and form an
intramolecular CBS pair. The interface between the two
CBS domains forms a cleft that is a potential ligand
binding site. The CBS pair coexists with a variety of
other functional domains and this has been used to help
in its classification here. It has been proposed that
the CBS domain may play a regulatory role, although its
exact function is unknown. Mutations of conserved
residues within this domain are associated with a
variety of human hereditary diseases, including
congenital myotonia, idiopathic generalized epilepsy,
hypercalciuric nephrolithiasis, and classic Bartter
syndrome (CLC chloride channel family members),
Wolff-Parkinson-White syndrome (gamma 2 subunit of
AMP-activated protein kinase), retinitis pigmentosa (IMP

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

which is involved in bacterial cell wall metabolism.

>gnl|CDD|199864 cd06240, M14-like_1_3, Peptidase M14-like domain; uncharacterized
subgroup. Peptidase M14-like domain of 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.

desuccinylase (ASTE)/aspartoacylase (ASPA)-like;
uncharacterized subgroup. A functionally
uncharacterized subgroup of the Succinylglutamate
desuccinylase (ASTE)/aspartoacylase (ASPA) subfamily
which is part of the M14 family of
metallocarboxypeptidases. ASTE catalyzes the fifth and
last step in arginine catabolism by the arginine
succinyltransferase pathway, and aspartoacylase (ASPA,
also known as aminoacylase 2, and ACY-2; EC:3.5.1.15)
cleaves N-acetyl L-aspartic acid (NAA) into aspartate
and acetate. NAA is abundant in the brain, and
hydrolysis of NAA by ASPA may help maintain white
matter. ASPA is an NAA scavenger in other tissues.
Mutations in the gene encoding ASPA cause Canavan
disease (CD), a fatal progressive neurodegenerative
disorder involving dysmyelination and spongiform
degeneration of white matter in children. This enzyme
binds zinc which is necessary for activity. Measurement
of elevated NAA levels in urine is used in the diagnosis
of CD.

>gnl|CDD|199841 cd03856, M14_Nna1_like, Peptidase M14-like domain of ATP/GTP
binding proteins, cytosolic carboxypeptidases and
related proteins. Peptidase M14-like domain of Nna-1
(Nervous system Nuclear protein induced by Axotomy),
also known as ATP/GTP binding protein (AGTPBP-1) and
cytosolic carboxypeptidase (CCP), and related proteins.
The Peptidase M14 family of metallocarboxypeptidases 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. This subfamily includes the human AGTPBP-1
and AGBL -2, -3, -4, and -5, and the mouse Nna1/CCP-1
and CCP -2 through -6. Nna1-like proteins are active
metallopeptidases that are thought to act on cytosolic
proteins such as alpha-tubulin, to remove a C-terminal
tyrosine. Nna1 is widely expressed in the developing and
adult nervous systems, including cerebellar Purkinje and
granule neurons, miral cells of the olfactory bulb and
retinal photoreceptors. Nna1 is also induced in
axotomized motor neurons. Mutations in Nna1 cause
Purkinje cell degeneration (pcd). The Nna1 CP domain is
required to prevent the retinal photoreceptor loss and
cerebellar ataxia phenotypes of pcd mice, and a
functional zinc-binding domain is needed for Nna-1 to
support neuron survival in these mice. Nna1-like
proteins from the different phyla are highly diverse,
but they all contain a characteristic N-terminal
conserved domain right before the CP domain. It has been
suggested that this N-terminal domain might act as a
folding domain.
