>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|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|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.

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

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.

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.

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.

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. 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.

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.

which hydrolyze single, C-terminal amino acids from

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

Peptide Amidase A (MpaA) and related proteins. MpaA is a
member of the M14 family of metallocarboxypeptidases
(MCPs), however it has an exceptional type of activity,
it hydrolyzes the gamma-D-glutamyl-meso-diaminopimelic
acid (gamma-D-Glu-Dap) bond in murein peptides. MpaA is
specific for cleavage of the gamma-D-Glu-Dap bond of
free murein tripeptide; it may also cleave murein
tetrapeptide. MpaA has a different substrate specificity
and cellular role than endopeptidase I, ENP1 (ENP1 does
not belong to this group). MpaA works on free murein
peptide in the recycling pathway.

>gnl|CDD|199863 cd06239, M14-like_1_2, 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 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.

(MCPs). The M14 family are zinc-binding CPs which
hydrolyze single, C-terminal amino acids from

as a stable zymogen in the pancreatic granules until
secretion into the digestive tract occurs. This
subfamily includes CPA1, CPA2 and CPA4 forms. Within
these A forms, there are slightly different

aromatic residues, and CPA2 preferring the bulkier
aromatic side chains. CPA4, detected in
hormone-regulated tissues, is thought to play a role in
prostate cancer.

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.

>gnl|CDD|199853 cd03872, M14_CPA6, Peptidase M14 carboxypeptidase subfamily
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.

AotO. An uncharacterized subgroup of the
Succinylglutamate desuccinylase (ASTE)/aspartoacylase
(ASPA) subfamily which is part of the the M14 family of
metallocarboxypeptidases. This subgroup includes
Pseudomonas aeruginosa AotO and related proteins. 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. The gene encoding P. aeruginosa AotO was
characterized as part of an operon encoding an arginine
and ornithine transport system, however it is not
essential for arginine and ornithine uptake.

>gnl|CDD|199862 cd06238, M14-like_1_1, 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 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.

ATP/GTP binding protein (AGTPBP-1/Nna1)-like proteins
are active metallopeptidases that are thought to act on
cytosolic proteins such as alpha-tubulin, to remove a
C-terminal tyrosine. Mutations in AGTPBP-1/Nna1 cause
Purkinje cell degeneration (pcd). AGTPBP-1/Nna1 however
does not belong to this subgroup. AGTPBP-1/Nna1-like

>gnl|CDD|199872 cd06252, M14_ASTE_ASPA_like_2, Peptidase M14 Succinylglutamate
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.
