>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.

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

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.

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.

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.

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.

>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.

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.

(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.

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

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

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.

zinc-binding carboxypeptidases (CPs) which hydrolyze
single, C-terminal amino acids from polypeptide chains,
and have a recognition site for the free C-terminal

favor hydrophobic residues while carboxypeptidase B-like
(CPB-like) enzymes only cleave the basic residues lysine

They contain an extra C-terminal transthyretin-like

Nna1/AGTPBP-1, AGBL2 -5, and related proteins. Subgroup
of the 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 eukaryotic subgroup includes the human
Nna1/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 unique N-terminal conserved
domain right before the CP domain. It has been suggested
that this N-terminal domain might act as a folding
domain.

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.

N/E-like; Carboxypeptidase D, domain II subgroup. The
second carboxypeptidase (CP)-like domain of
Carboxypeptidase D (CPD; EC 3.4.17.22), domain II. 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, while 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 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.

specific for cleavage of the gamma-D-Glu-Dap bond of
free murein tripeptide; it may also cleave murein

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.

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.

hydrolyze single, C-terminal amino acids from

glycoprotein, bound to cell membranes via a

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.

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.

Pleckstrin Homology-Glucosyltransferases, Rab-like
GTPase activators and Myotubularins (PH-GRAM) domain.
C2GRAM contains two N-terminal C2 domains followed by a
single PH-GRAM domain. Since it contains both of these
domains it is assumed that this gene cross-links both
calcium and phosphoinositide signaling pathways. In
general he C2 domain is involved in binding
phospholipids in a calcium dependent manner or calcium
independent manner. The GRAM domain is found in
glucosyltransferases, myotubularins and other putative
membrane-associated proteins. The GRAM domain is part of
a larger motif with a pleckstrin homology (PH) domain
fold.

Protein Serine/Threonine Kinases. Serine/threonine

is part of a larger superfamily that includes the
catalytic domains of other protein STKs, protein
tyrosine kinases, RIO kinases, aminoglycoside

3-kinase. Members of the subfamily include SLK, STK10
(also called LOK for lymphocyte-oriented kinase), SmSLK
(Schistosoma mansoni SLK), and related proteins. SLK
promotes apoptosis through apoptosis signal-regulating
kinase 1 (ASK1) and the mitogen-activated protein kinase
(MAPK) p38. It also plays a role in mediating actin
reorganization. STK10 is responsible in regulating the
CD28 responsive element in T cells, as well as leukocyte
function associated antigen (LFA-1)-mediated lymphocyte
adhesion. SmSLK is capable of activating the MAPK Jun
N-terminal kinase (JNK) pathway in human embryonic
kidney (HEK) cells as well as in Xenopus oocytes. It may
participate in regulating MAPK cascades during
host-parasite interactions.

archaeal Aminoacyclase-1 indole-3-acetic-L-aspartic acid
hydrolase (IAA-Asp hydrolase; IAAspH; IAAH; IAA

indole-3-acetyl-N-aspartic acid (IAA or auxin) to
indole-3-acetic acid. Genes encoding IAA-amidohydrolases
were first cloned from Arabidopsis; ILR1, IAR3, ILL1 and
ILL2 encode active IAA- amino acid hydrolases, and three
additional amidohydrolase-like genes (ILL3, ILL5, ILL6)
have been isolated. In higher plants, the growth
regulator indole-3-acetic acid (IAA or auxin) is found
both free and conjugated via amide bonding to a variety
of amino acids and peptides, and via an ester linkage to
carbohydrates. IAA-Asp conjugates are involved in
homeostatic control, protection, storing and subsequent
use of free IAA. IAA-Asp is also found in some plants as
a unique intermediate for entering into IAA
non-decarboxylative oxidative pathway. IAA
amidohydrolase cleaves the amide bond between the auxin
and the conjugated amino acid. Enterobacter agglomerans
IAAspH has very strong enzyme activity and substrate
specificity towards IAA-Asp, although its substrate
affinity is weaker compared to Arabidopsis enzymes of
the ILR1 gene family. Enhanced IAA-hydrolase activity
has been observed during clubroot disease in Chinese
cabbage.

binding protein AGBL-2 and AGBL-3, and related proteins.
Peptidase M14-like domain of ATP/GTP binding
protein_like (AGBL)-2, 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 subgroup includes the human AGBL-2,
and -3, and the mouse cytosolic carboxypeptidase
(CCPs)-2, and -3. 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 proteins
from the different phyla are highly diverse, but they
all contain a unique N-terminal conserved domain right
before the CP domain. It has been suggested that this
N-terminal domain might act as a folding domain.
