>gnl|CDD|189008 cd09601, M1_APN_2, Peptidase M1 Aminopeptidase N family incudes
tricorn interacting factor F3, Endoplasmic reticulum
aminopeptidase 1 (ERAP1), Aminopeptidase Q (APQ). This
M1 peptidase family includes eukaryotic and bacterial
members: aminopeptidase N (APN), aminopeptidase Q (APQ,
laeverin), endoplasmic reticulum aminopeptidase 1
(ERAP1) as well as tricorn interacting factor F3.
Aminopeptidase N (APN; CD13; Alanyl aminopeptidase; EC
3.4.11.2), a Type II integral membrane protease,
consists of a small N-terminal cytoplasmic domain, a
single transmembrane domain and a large extracellular
ectodomain that contains the active site. It
preferentially cleaves neutral amino acids from the
N-terminus of oligopeptides and is present in a variety
of human tissues and cell types (leukocyte, fibroblast,
endothelial and epithelial cells). APN expression is
dysregulated in inflammatory diseases such as chronic
pain, rheumatoid arthritis, multiple sclerosis, systemic
sclerosis, systemic lupus erythematosus,
polymyositis/dermatomyosytis and pulmonary sarcoidosis,
and is enhanced in tumor cells such as melanoma, renal,
prostate, pancreas, colon, gastric and thyroid cancers.
It is considered a marker of differentiation since it is
predominantly expressed on stem cells and on cells of
the granulocytic and monocytic lineages at distinct
stages of differentiation. Thus, APN inhibition may lead
to the development of anti-cancer and anti-inflammatory
drugs. ERAP1 also known as endoplasmic reticulum
aminopeptidase associated with antigen processing
(ERAAP), adipocyte derived leucine aminopeptidase
(A-LAP) or aminopeptidase regulating tumor necrosis
factor receptor I (THFRI) shedding (ARTS-1), associates
with the closely related ER aminopeptidase ERAP2, for
the final trimming of peptides within the ER for
presentation by MHC class I molecules. ERAP1 is
associated with ankylosing spondylitis (AS), an
inflammatory arthritis that predominantly affects the
spine. ERAP1 also aids in the shedding of membrane-bound
cytokine receptors. The tricorn interacting factor F3,
together with factors F1 and F2, degrades the tricorn
protease products, producing free amino acids, thus
completing the proteasomal degradation pathway. F3 is
homologous to F2, but not F1, and shows a strong
preference for glutamate in the P1' position. APQ, also
known as laeverin, is specifically expressed in human
embryo-derived extravillous trophoblasts (EVTs) that
invade the uterus during early placentation. It cleaves
the N-terminal amino acid of various peptides such as
angiotensin III, endokinin C, and kisspeptin-10, all
expressed in the placenta in large quantities. APN is a
receptor for coronaviruses, although the virus receptor
interaction site seems to be distinct from the enzymatic
site and aminopeptidase activity is not necessary for
viral infection. APNs are also putative Cry toxin
receptors. Cry1 proteins are pore-forming toxins that
bind to the midgut epithelial cell membrane of
susceptible insect larvae, causing extensive damage.
Several different toxins, including Cry1Aa, Cry1Ab,
Cry1Ac, Cry1Ba, Cry1Ca and Cry1Fa, have been shown to
bind to APNs; however, a direct role of APN in
cytotoxicity has been yet to be firmly established.

leukotriene A4 hydrolase. M1 Peptidase family includes
aminopeptidase N (APN) and leukotriene A4 hydrolase
(LTA4H). All peptidases in this family bind a single
catalytic zinc ion which is tetrahedrally co-ordinated
by three amino acid ligands and a water molecule that
forms the nucleophile on activation during catalysis.
APN consists of a small N-terminal cytoplasmic domain, a

possessing an aminopeptidase as well as an epoxide
hydrolase activity. The two activities occupy different,
but overlapping sites. The activity and physiological
relevance of the aminopeptidase in LTA4H is as yet
unknown while the epoxide hydrolase converts leukotriene
A4 (LTA4) into leukotriene B4 (LTB4), a potent

hydrolase (LTA4H; E.C. 3.3.2.6) and the close homolog
cold-active aminopeptidase (Colwellia
psychrerythraea-type peptidase; ColAP), both members of
the aminopeptidase M1 family. LTA4H, is a bifunctional
enzyme possessing an aminopeptidase as well as an
epoxide hydrolase activity. The two activities occupy
different, but overlapping sites. The activity and
physiological relevance of the aminopeptidase is as yet
unknown while the epoxide hydrolase converts leukotriene
A4 (LTA4) into leukotriene B4 (LTB4), a potent
chemotaxin that is fundamental to the inflammatory
response of mammals. It accepts a variety of substrates,
including some opioid, di- and tripeptides, as well as
chromogenic aminoacyl-p-nitroanilide derivatives. The
aminopeptidase activity of LTA4H is possibly involved in
the processing of peptides related to inflammation and
host defense. Kinetic analysis shows that LTA4H
hydrolyzes arginyl tripeptides with high efficiency and
specificity, indicating its function as an arginyl
aminopeptidase. LTA4H is overexpressed in certain human
cancers, and has been identified as a functionally
important target for mediating anticancer properties of
resveratrol, a well known red wine polyphenolic compound
with cancer chemopreventive activity.

>gnl|CDD|189018 cd09839, M1_TAF2, TATA binding protein (TBP) associated factor 2.
This family includes TATA binding protein (TBP)
associated factor 2 (TAF2, TBP-associated factor
TAFII150, transcription initiation factor TFIID subunit
2, RNA polymerase II TBP-associated factor subunit B),
and has homology to the aminopeptidase N (APN)
subfamily, belonging to the M1 gluzincin family. TAF2 is
part of the TFIID multidomain subunit complex essential
for transcription of most protein-encoded genes by RNA
polymerase II. TAF2 is known to interact with the
initiator element (Inr) found at the transcription start
site of many genes, thus possibly playing a key role in
promoter binding as well as start-site selection. Image
analysis has shown TAF2 to form a complex with TAF1 and
TBP, inferring its role in promoter recognition.
Peptidases in the M1 family bind a single catalytic zinc
ion which is tetrahedrally co-ordinated by three amino
acid ligands and a water molecule that forms the
nucleophile on activation during catalysis. TAF2,
however, does not seem to contain any of the active site
residues.

>gnl|CDD|189011 cd09604, M1_APN_5, Peptidase M1 family containing bacterial
Aminopeptidase N. This family contains bacterial
aminopeptidase N (APN; CD13; Alanyl aminopeptidase; EC
3.4.11.2), a Type II integral membrane protease
belonging to the M1 gluzincin family. APN consists of a
small N-terminal cytoplasmic domain, a single
transmembrane domain and a large extracellular
ectodomain that contains the active site. It
preferentially cleaves neutral amino acids from the
N-terminus of oligopeptides and, in higher eukaryotes,
is present in a variety of human tissues and cell types
(leukocyte, fibroblast, endothelial and epithelial
cells). APN expression is dysregulated in inflammatory
diseases such as chronic pain, rheumatoid arthritis,
multiple sclerosis, systemic sclerosis, systemic lupus
erythematosus, polymyositis/dermatomyosytis and
pulmonary sarcoidosis, and is enhanced in tumor cells
such as melanoma, renal, prostate, pancreas, colon,
gastric and thyroid cancers. It is predominantly
expressed on stem cells and on cells of the granulocytic
and monocytic lineages at distinct stages of
differentiation, thus considered a marker of
differentiation. Thus, APN inhibition may lead to the
development of anti-cancer and anti-inflammatory drugs.
APNs are also present in many pathogenic bacteria and
represent potential drug targets, Some APNs have been
used commercially, such as one from Lactococcus lactis
used in the food industry. APN also serves as a receptor
for coronaviruses, although the virus receptor
interaction site seems to be distinct from the enzymatic
site and aminopeptidase activity is not necessary for
viral infection. APNs have also been extensively studied
as putative Cry toxin receptors. Cry1 proteins are
pore-forming toxins that bind to the midgut epithelial
cell membrane of susceptible insect larvae, causing
extensive damage. Several different toxins, including
Cry1Aa, Cry1Ab, Cry1Ac, Cry1Ba, Cry1Ca and Cry1Fa, have
been shown to bind to APNs; however, a direct role of
APN in cytotoxicity has been yet to be firmly
established.

The M1 family of zinc metallopeptidases contains a
number of distinct, well-separated clades of proteins
with aminopeptidase activity. Several are designated
aminopeptidase N, EC 3.4.11.2, after the Escherichia
coli enzyme, suggesting a similar activity profile (see
SP|P04825 for a description of catalytic activity). This
family consists of all aminopeptidases closely related
to E. coli PepN and presumed to have similar (not
identical) function. Nearly all are found in
Proteobacteria, but members are found also in
Cyanobacteria, plants, and apicomplexan parasites. This
family differs greatly in sequence from the family of
aminopeptidases typified by Streptomyces lividans PepN
(TIGR02412), from the membrane bound aminopeptidase N
family in animals, etc [Protein fate, Degradation of
proteins, peptides, and glycopeptides].

proteinases, TLPs) includes peptidases M1, M2, M3, M4,
M13, M32 and M36 (fungalysins). Gluzincin family
(thermolysin-like peptidases or TLPs) includes several
zinc-dependent metallopeptidases such as the M1, M2, M3,
M4, M13, M32, M36 peptidases (MEROPS classification),
and contain HEXXH and EXXXD motifs as part of their
active site. All peptidases in this family bind a single
catalytic zinc ion which is tetrahedrally co-ordinated
by three amino acid ligands and a water molecule that
forms the nucleophile on activation during catalysis. M1
family includes aminopeptidase N (APN) and leukotriene
A4 hydrolase (LTA4H). APN preferentially cleaves
neutral amino acids from the N-terminus of oligopeptides
and is present in a variety of human tissues and cell
types. LTA4H is a bifunctional enzyme, possessing an
aminopeptidase as well as an epoxide hydrolase activity
such that the two activities occupy different, but
overlapping sites. The peptidase M3 or neurolysin-like
family, includes M3, M2 and M32 metallopeptidases. The
M3 peptidases have two subfamilies: M3A, includes thimet
oligopeptidase (TOP; endopeptidase 3.4.24.15),
neurolysin (3.4.24.16), and the mitochondrial
intermediate peptidase; M3B contains oligopeptidase F.
M2 peptidase angiotensin converting enzyme (ACE, EC
3.4.15.1) catalyzes the conversion of decapeptide
angiotensin I to the potent vasopressor octapeptide
angiotensin II. ACE is a key part of the
renin-angiotensin system that regulates blood pressure,
thus ACE inhibitors are important for the treatment of
hypertension. M32 family includes two eukaryotic enzymes
from protozoa Trypanosoma cruzi, a causative agent of
Chagas' disease, and Leishmania major, a parasite that
causes leishmaniasis, making them attractive targets for
drug development. The M4 family includes secreted
protease thermolysin (EC 3.4.24.27), pseudolysin,
aureolysin, neutral protease as well as fungalysin and
bacillolysin (EC 3.4.24.28) that degrade extracellular
proteins and peptides for bacterial nutrition,
especially prior to sporulation. Thermolysin is widely
used as a nonspecific protease to obtain fragments for
peptide sequencing as well as in production of the
artificial sweetener aspartame. M13 family includes
neprilysin (EC 3.4.24.11) and endothelin-converting
enzyme I (ECE-1, EC 3.4.24.71), which fulfill a broad
range of physiological roles due to the greater
variation in the S2' subsite allowing substrate
specificity and are prime therapeutic targets for
selective inhibition. Peptidase M36 (fungamysin) family
includes endopeptidases from pathogenic fungi.
Fungalysin hydrolyzes extracellular matrix proteins such
as elastin and keratin. Aspergillus fumigatus causes the
pulmonary disease aspergillosis by invading the lungs of
immuno-compromised animals and secreting fungalysin that
possibly breaks down proteinaceous structural barriers.

>gnl|CDD|238737 cd01460, vWA_midasin, VWA_Midasin: Midasin is a member of the AAA
ATPase family. The proteins of this family are unified
by their common archetectural organization that is based
upon a conserved ATPase domain. The AAA domain of
midasin contains six tandem AAA protomers. The AAA
domains in midasin is followed by a D/E rich domain that
is following by a VWA domain. The members of this
subgroup have a conserved MIDAS motif. The function of
this domain is not exactly known although it has been
speculated to play a crucial role in midasin function.
