>gnl|CDD|173789 cd04059, Peptidases_S8_Protein_convertases_Kexins_Furin-like,
Peptidase S8 family domain in Protein convertases.
Protein convertases, whose members include furins and
kexins, are members of the peptidase S8 or Subtilase
clan of proteases. They have an Asp/His/Ser catalytic
triad that is not homologous to trypsin. Kexins are
involved in the activation of peptide hormones, growth
factors, and viral proteins. Furin cleaves cell surface
vasoactive peptides and proteins involved in
cardiovascular tissue remodeling in the TGN, at cell
surface, or in endosomes but rarely in the ER. Furin
also plays a key role in blood pressure regulation
though the activation of transforming growth factor
(TGF)-beta. High specificity is seen for cleavage after
dibasic (Lys-Arg or Arg-Arg) or multiple basic residues
in protein convertases. There is also strong sequence
conservation.

Members of the peptidase S53 (sedolisin) family include
endopeptidases and exopeptidases. The S53 family
contains a catalytic triad Glu/Asp/Ser with an
additional acidic residue Asp in the oxyanion hole,
similar to that of Asn in subtilisin. The stability of
these enzymes may be enhanced by calcium, some members
have been shown to bind up to 4 ions via binding sites
with different affinity. Some members of this clan
contain disulfide bonds. These enzymes can be intra- and
extracellular, some function at extreme temperatures and
pH values. Characterized sedolisins include Kumamolisin,
an extracellular calcium-dependent thermostable
endopeptidase from Bacillus. The enzyme is synthesized
with a 188 amino acid N-terminal preprotein region which
is cleaved after the extraction into the extracellular
space with low pH. One kumamolysin paralog,
kumamolisin-As, is believed to be a collagenase. TPP1 is
a serine protease that functions as a tripeptidyl
exopeptidase as well as an endopeptidase. Less is known
about PSCP from Pseudomonas which is thought to be an
aspartic proteinase.

catalytic triad similar to that found in trypsin-like

The serine residue here is the nucleophilic equivalent

However, the aspartic acid residue that acts as an

others are extracellular, some function at extreme

region which is cleaved after the extraction into the
extracellular space with low pH. One kumamolysin
paralog, kumamolisin-As, is believed to be a
collagenase. TPP1 is a serine protease that functions as
a tripeptidyl exopeptidase as well as an endopeptidase.
Less is known about PSCP from Pseudomonas which is
thought to be an aspartic proteinase.

domain in Subtilisin proteins. This group is composed
of many different subtilisins: Pro-TK-subtilisin,
subtilisin Carlsberg, serine protease Pb92 subtilisin,
and BPN subtilisins just to name a few.
Pro-TK-subtilisin is a serine protease from the
hyperthermophilic archaeon Thermococcus kodakaraensis
and consists of a signal peptide, a propeptide, and a
mature domain. TK-subtilisin is matured from
pro-TK-subtilisin upon autoprocessing and degradation
of the propeptide. Unlike other subtilisins though, the
folding of the unprocessed form of pro-TK-subtilisin is
induced by Ca2+ binding which is almost completed prior
to autoprocessing. Ca2+ is required for activity unlike
the bacterial subtilisins. The propeptide is not
required for folding of the mature domain unlike the
bacterial subtilases because of the stability produced
from Ca2+ binding. Subtilisin Carlsberg is extremely
similar in structure to subtilisin BPN'/Novo thought it
has a 30% difference in amino acid sequence. The
substrate binding regions are also similar and 2
possible Ca2+ binding sites have been identified
recently. Subtilisin Carlsberg possesses the highest
commercial importance as a proteolytic additive for
detergents. Serine protease Pb92, the serine protease
from the alkalophilic Bacillus strain PB92, also
contains two calcium ions and the overall folding of
the polypeptide chain closely resembles that of the
subtilisins. Members of the peptidases S8 and S35
clan include endopeptidases, exopeptidases and also a
tripeptidyl-peptidase. The S8 family has an Asp/His/Ser
catalytic triad similar to that found in trypsin-like

of the Peptidases S8 or Subtilases serine endo- and
exo-peptidase clan. They have an Asp/His/Ser catalytic
triad similar to that found in trypsin-like proteases,
but do not share their three-dimensional structure and
are not homologous to trypsin. The stability of
subtilases may be enhanced by calcium, some members
have been shown to bind up to 4 ions via binding sites
with different affinity. Some members of this clan
contain disulfide bonds. These enzymes can be intra-
and extracellular, some function at extreme
temperatures and pH values.

Pseudomonas-type. Members of this protein family are
bacterial, phosphatidylcholine-hydrolyzing phospholipase
C enzymes, with a characteristic domain architecture as
found in hemolytyic (PlcH) and nonhemolytic (PlcN)
secreted enzymes of Pseudomonas aeruginosa. PlcH
hydrolyzes phosphatidylcholine to diacylglycerol and
phosphocholine, but unlike PlcN can also hydrolyze
sphingomyelin to ceramide ((N-acylsphingosine)) and
phosphocholine. Members of this family share the
twin-arginine signal sequence for Sec-independent
transport across the plasma membrane. PlcH is secreted
as a heterodimer with a small chaperone, PlcR, encoded
immediately downstream [Cellular processes,
Pathogenesis].
