>gnl|CDD|201774 pfam01401, Peptidase_M2, Angiotensin-converting enzyme. Members of
this family are dipeptidyl carboxydipeptidases (cleave
carboxyl dipeptides) and most notably convert
angiotensin I to angiotensin II. Many members of this
family contain a tandem duplication of the 600 amino
acid peptidase domain, both of these are catalytically
active. Most members are secreted membrane bound
ectoenzymes.

>gnl|CDD|188999 cd06461, M2_ACE, Peptidase family M2 Angiotensin converting enzyme
(ACE). Peptidase family M2 Angiotensin converting
enzyme (ACE, EC 3.4.15.1) is a membrane-bound, zinc
dependent dipeptidase that catalyzes the conversion of
the decapeptide angiotensin I to the potent vasopressor
octapeptide angiotensin II, by removing two C-terminal
amino acids. There are two forms of the enzyme in
humans, the ubiquitous somatic ACE and the
sperm-specific germinal ACE, both encoded by the same
gene through transcription from alternative promoters.
Somatic ACE has two tandem active sites with distinct
catalytic properties, whereas germinal ACE, the function
of which is largely unknown, has just a single active
site. Recently, an ACE homolog, ACE2, has been
identified in humans that differs from ACE; it
preferentially removes carboxy-terminal hydrophobic or
basic amino acids and appears to be important in cardiac
function. ACE homologs (also known as members of the M2
gluzincin family) have been found in a wide variety of
species, including those that neither have a
cardiovascular system nor synthesize angiotensin. ACE is
well-known as a key part of the renin-angiotensin system
that regulates blood pressure and ACE inhibitors are
important for the treatment of hypertension.

>gnl|CDD|188993 cd06258, M3_like, Peptidase M3-like family, a zincin
metallopeptidase, includes M3 and M32 families. The
peptidase M3-like family, also called neurolysin-like
family, is part of the "zincins" metallopeptidases, and
includes M3 and M32 families of metallopeptidases. The
M3 family is subdivided into two subfamilies: the
widespread M3A, which comprises a number of
high-molecular mass endo- and exopeptidases from
bacteria, archaea, protozoa, fungi, plants and animals,
and the small M3B, whose members are enzymes primarily
from bacteria. Well-known mammalian/eukaryotic M3A
endopeptidases are the thimet oligopeptidase (TOP;
endopeptidase 3.4.24.15), neurolysin (alias
endopeptidase 3.4.24.16), and the mitochondrial
intermediate peptidase. The first two are intracellular
oligopeptidases, which act only on relatively short
substrates of less than 20 amino acid residues, while
the latter cleaves N-terminal octapeptides from proteins
during their import into the mitochondria. The M3A
subfamily also contains several bacterial
endopeptidases, collectively called oligopeptidases A,
as well as a large number of bacterial
carboxypeptidases, called dipeptidyl peptidases (Dcp;
Dcp II; peptidyl dipeptidase; EC 3.4.15.5). The
peptidases in the M3 family contain the HEXXH motif that
forms the active site in conjunction with a
C-terminally-located Glutamic acid (Glu) residue. A
single zinc ion is ligated by the side-chains of the two
Histidine (His) residues, and the more C-terminal Glu.
Most of the peptidases are synthesized without signal
peptides or propeptides, and function intracellularly.
There are similarities to the thermostable
carboxypeptidases from Pyrococcus furiosus
carboxypeptidase (PfuCP), and Thermus aquaticus (TaqCP),
belonging to peptidase family M32. Little is known about
function of this family, including carboxypeptidases Taq
and Pfu.

>gnl|CDD|189001 cd09594, GluZincin, Peptidase Gluzincin family (thermolysin-like
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|143587 cd07197, nitrilase, Nitrilase superfamily, including nitrile- or
amide-hydrolyzing enzymes and amide-condensing enzymes.
This superfamily (also known as the C-N hydrolase
superfamily) contains hydrolases that break
carbon-nitrogen bonds; it includes nitrilases, cyanide
dihydratases, aliphatic amidases, N-terminal amidases,
beta-ureidopropionases, biotinidases, pantotheinase,
N-carbamyl-D-amino acid amidohydrolases, the glutaminase
domain of glutamine-dependent NAD+ synthetase,
apolipoprotein N-acyltransferases, and
N-carbamoylputrescine amidohydrolases, among others.
These enzymes depend on a Glu-Lys-Cys catalytic triad,
and work through a thiol acylenzyme intermediate.
Members of this superfamily generally form homomeric
complexes, the basic building block of which is a
homodimer. These oligomers include dimers, tetramers,
hexamers, octamers, tetradecamers, octadecamers, as well
as variable length helical arrangements and
homo-oligomeric spirals. These proteins have roles in
vitamin and co-enzyme metabolism, in detoxifying small
molecules, in the synthesis of signaling molecules, and
in the post-translational modification of proteins. They
are used industrially, as biocatalysts in the fine
chemical and pharmaceutical industry, in cyanide
remediation, and in the treatment of toxic effluent.
This superfamily has been classified previously in the
literature, based on global and structure-based sequence
analysis, into thirteen different enzyme classes
(referred to as 1-13). This hierarchy includes those
thirteen classes and a few additional subfamilies. A
putative distant relative, the plasmid-borne TraB
family, has not been included in the hierarchy.

>gnl|CDD|212840 cd11907, SH3_TXK, Src Homology 3 domain of TXK, also called Resting
lymphocyte kinase (Rlk). TXK is a cytoplasmic (or
nonreceptor) tyr kinase containing Src homology protein
interaction domains (SH3, SH2) N-terminal to the
catalytic tyr kinase domain. It also contains an
N-terminal cysteine-rich region. Rlk is expressed in
T-cells and mast cell lines, and is a key component of
T-cell receptor (TCR) signaling. It is important in
TCR-stimulated proliferation, IL-2 production and
phospholipase C-gamma1 activation. SH3 domains are
protein interaction domains that bind to proline-rich
ligands with moderate affinity and selectivity,
preferentially to PxxP motifs. They play versatile and
diverse roles in the cell including the regulation of
enzymes, changing the subcellular localization of
signaling pathway components, and mediating the
formation of multiprotein complex assemblies.
