metalloprotease. The members of this family are enzymes
that cleave peptides. These proteases require zinc for
catalysis. Members of this family are also known as
adamalysins. Most members of this family are snake venom
endopeptidases, but there are also some mammalian
proteins such as human ADAM8 and fertilin. Fertilin and
closely related proteins appear to not have some active
site residues and may not be active enzymes.

ADAMTS_like subgroup. ADAMs (A Disintegrin And
Metalloprotease) are glycoproteins, which play roles in
cell signaling, cell fusion, and cell-cell interactions.
This particular subfamily represents domain
architectures that combine ADAM-like metalloproteinases
with thrombospondin type-1 repeats. ADAMTS (a
disintegrin and metalloproteinase with thrombospondin
motifs) proteinases are inhibited by TIMPs (tissue
inhibitors of metalloproteinases), and they play roles
in coagulation, angiogenesis, development and
progression of arthritis. They hydrolyze the von
Willebrand factor precursor and various components of
the extracellular matrix.

>gnl|CDD|213029 cd11375, Peptidase_M54, Peptidase family M54, also called
archaemetzincins or archaelysins. Peptidase M54
(archaemetzincin or archaelysin) is a zinc-dependent
aminopeptidase that contains the consensus zinc-binding
sequence HEXXHXXGXXH/D and a conserved Met residue at
the active site, and is thus classified as a metzincin.
Archaemetzincins, first identified in archaea, are also
found in bacteria and eukaryotes, including two human
members, archaemetzincin-1 and -2 (AMZ1 and AMZ2). AMZ1
is mainly found in the liver and heart while AMZ2 is
primarily expressed in testis and heart; both have been
reported to degrade synthetic substrates and peptides.
The Peptidase M54 family contains an extended metzincin
concensus sequence of HEXXHXXGX3CX4CXMX17CXXC such that
a second zinc ion is bound to four cysteines, thus
resembling a zinc finger. Phylogenetic analysis of this
family reveals a complex evolutionary process involving
a series of lateral gene transfer, gene loss and genetic
duplication events.

CLECT_thrombomodulin_like: C-type lectin-like domain
(CTLD) of the type found in human thrombomodulin(TM),
Endosialin, C14orf27, and C1qR. CTLD refers to a domain
homologous to the carbohydrate-recognition domains
(CRDs) of the C-type lectins. In these
thrombomodulin-like proteins the residues involved in
coordinating Ca2+ in the classical MBP-A CTLD are not
conserved. TM exerts anti-fibrinolytic and
anti-inflammatory activity. TM also regulates blood
coagulation in the anticoagulant protein C pathway. In
this pathway, the procoagulant properties of thrombin
(T) are lost when it binds TM. TM also plays a key role
in tumor biology. It is expressed on endothelial cells
and on several type of tumor cell including squamous
cell carcinoma. Loss of TM expression correlates with
advanced stage and poor prognosis. Loss of function of
TM function may be associated with arterial or venous
thrombosis and with late fetal loss. Soluble molecules
of TM retaining the CTLD are detected in human plasma
and urine where higher levels indicate injury and/or
enhanced turnover of the endothelium. C1qR is expressed
on endothelial cells and stem cells. It is also
expressed on monocots and neutrophils, where it is
subject to ectodomain shedding. Soluble forms of C1qR
retaining the CTLD is detected in human plasma. C1qR
modulates the phagocytosis of apoptotic cells in vivo.
C1qR-deficient mice are defective in clearance of
apoptotic cells in vivo. The cytoplasmic tail of C1qR,
C-terminal to the CTLD of CD93, contains a PDZ binding
domain which interacts with the PDZ domain-containing
adaptor protein, GIPC. The juxtamembrane region of this
tail interacts with the ezrin/radixin/moesin family.
Endosialin functions in the growth and progression of
abdominal tumors and is expressed in the stroma of
several tumors.

>gnl|CDD|239589 cd03512, Alkane-hydroxylase, Alkane hydroxylase is a bacterial,
integral-membrane di-iron enzyme that shares a
requirement for iron and oxygen for activity similar to
that of the non-heme integral-membrane acyl coenzyme A
(CoA) desaturases and acyl lipid desaturases. The alk
genes in Pseudomonas oleovorans encode conversion of
alkanes to acyl CoA. The alkane omega-hydroxylase (AlkB)
system is responsible for the initial oxidation of
inactivated alkanes. It is a three-component system
comprising a soluble NADH-rubredoxin reductase (AlkT), a
soluble rubredoxin (AlkG), and the integral membrane
oxygenase (AlkB). AlkB utilizes the oxygen rebound
mechanism to hydroxylate alkanes. This mechanism
involves homolytic cleavage of the C-H bond by an
electrophilic metal-oxo intermediate to generate a
substrate-based radical. As with other members of this
superfamily, this domain family has extensive
hydrophobic regions that would be capable of spanning
the membrane bilayer at least twice. The active site
structure of AlkB is not known, however, spectroscopic
and genetic evidence points to a nitrogen-rich
coordination environment located in the cytoplasm with
as many as eight histidines coordinating the two iron
ions and a carboxylate residue bridging the two metals.
Like all other members of this superfamily, there are
eight conserved histidines seen in the histidine cluster
motifs: HXXXH, HXXXHH, and HXXHH. These histidine
residues are reported to be catalytically essential and
proposed to be the ligands for the iron atoms contained
within the homolog, stearoyl CoA desaturase. Also
included in this CD are terminal alkane hydroxylases
(AlkM), xylene monooxygenase hydroxylases (XylM),
p-cymene monooxygenase hydroxylases (CymAa), and other

tricorn interacting factor F3, Endoplasmic reticulum

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.
