>gnl|CDD|239313 cd03015, PRX_Typ2cys, Peroxiredoxin (PRX) family, Typical 2-Cys PRX
subfamily; PRXs are thiol-specific antioxidant (TSA)
proteins, which confer a protective role in cells
through its peroxidase activity by reducing hydrogen
peroxide, peroxynitrite, and organic hydroperoxides. The
functional unit of typical 2-cys PRX is a homodimer. A
unique intermolecular redox-active disulfide center is
utilized for its activity. Upon reaction with peroxides,
its peroxidatic cysteine is oxidized into a sulfenic
acid intermediate which is resolved by bonding with the
resolving cysteine from the other subunit of the
homodimer. This intermolecular disulfide bond is then
reduced by thioredoxin, tryparedoxin or AhpF. Typical
2-cys PRXs, like 1-cys PRXs, form decamers which are
stabilized by reduction of the active site cysteine.
Typical 2-cys PRX interacts through beta strands at one
edge of the monomer (B-type interface) to form the
functional homodimer, and uses an A-type interface
(similar to the dimeric interface in atypical 2-cys PRX
and PRX5) at the opposite end of the monomer to form the
stable decameric (pentamer of dimers) structure.

>gnl|CDD|211789 TIGR03137, AhpC, peroxiredoxin. This peroxiredoxin (AhpC,
alkylhydroperoxide reductase subunit C) is one subunit
of a two-subunit complex with subunit F(TIGR03140).
Usually these are found as an apparent operon. The gene
has been characterized in Bacteroides fragilis where it
is important in oxidative stress defense. This gene
contains two invariant cysteine residues, one near the
N-terminus and one near the C-terminus, each followed
immediately by a proline residue [Cellular processes,
Detoxification, Cellular processes, Adaptations to
atypical conditions].

>gnl|CDD|239269 cd02971, PRX_family, Peroxiredoxin (PRX) family; composed of the
different classes of PRXs including many proteins
originally known as bacterioferritin comigratory
proteins (BCP), based on their electrophoretic mobility
before their function was identified. PRXs are
thiol-specific antioxidant (TSA) proteins also known as
TRX peroxidases and alkyl hydroperoxide reductase C22
(AhpC) proteins. They confer a protective antioxidant
role in cells through their peroxidase activity in which
hydrogen peroxide, peroxynitrate, and organic
hydroperoxides are reduced and detoxified using reducing
equivalents derived from either TRX, glutathione,
trypanothione and AhpF. They are distinct from other
peroxidases in that they have no cofactors such as
metals or prosthetic groups. The first step of
catalysis, common to all PRXs, is the nucleophilic
attack by the catalytic cysteine (also known as the
peroxidatic cysteine) on the peroxide leading to
cleavage of the oxygen-oxygen bond and the formation of
a cysteine sulfenic acid intermediate. The second step
of the reaction, the resolution of the intermediate,
distinguishes the different types of PRXs. The presence
or absence of a second cysteine (the resolving cysteine)
classifies PRXs as either belonging to the 2-cys or
1-cys type. The resolving cysteine of 2-cys PRXs is
either on the same chain (atypical) or on the second
chain (typical) of a functional homodimer. Structural
and motif analysis of this growing family supports the
need for a new classification system. The peroxidase
activity of PRXs is regulated in vivo by irreversible
cysteine over-oxidation into a sulfinic acid,
phosphorylation and limited proteolysis.

>gnl|CDD|239314 cd03016, PRX_1cys, Peroxiredoxin (PRX) family, 1-cys PRX subfamily;
composed of PRXs containing only one conserved cysteine,
which serves as the peroxidatic cysteine. They are
homodimeric thiol-specific antioxidant (TSA) proteins
that confer a protective role in cells by reducing and
detoxifying hydrogen peroxide, peroxynitrite, and
organic hydroperoxides. As with all other PRXs, a
cysteine sulfenic acid intermediate is formed upon
reaction of 1-cys PRX with its substrates. Having no
resolving cysteine, the oxidized enzyme is resolved by
an external small-molecule or protein reductant such as
thioredoxin or glutaredoxin. Similar to typical 2-cys
PRX, 1-cys PRX forms a functional dimeric unit with a
B-type interface, as well as a decameric structure which
is stabilized in the reduced form of the enzyme. Other
oligomeric forms, tetramers and hexamers, have also been
reported. Mammalian 1-cys PRX is localized cellularly in
the cytosol and is expressed at high levels in brain,
eye, testes and lung. The seed-specific plant 1-cys PRXs
protect tissues from reactive oxygen species during
desiccation and are also called rehydrins.

subfamily; composed of proteins similar to Mycobacterium
tuberculosis AhpE. AhpE is described as a 1-cys PRX
because of the absence of a resolving cysteine. The

cysteine on the peroxide leading to the formation of a
cysteine sulfenic acid intermediate. The absence of a
resolving cysteine suggests that functional AhpE is
regenerated by an external reductant. The solution
behavior and crystal structure of AhpE show that it
forms dimers and octamers.

comigratory protein (BCP) subfamily; composed of
thioredoxin-dependent thiol peroxidases, widely
expressed in pathogenic bacteria, that protect cells
against toxicity from reactive oxygen species by
reducing and detoxifying hydroperoxides. The protein was
named BCP based on its electrophoretic mobility before
its function was known. BCP shows substrate selectivity
toward fatty acid hydroperoxides rather than hydrogen
peroxide or alkyl hydroperoxides. BCP contains the
peroxidatic cysteine but appears not to possess a
resolving cysteine (some sequences, not all, contain a
second cysteine but its role is still unknown). Unlike
other PRXs, BCP exists as a monomer. The plant homolog
of BCP is PRX Q, which is expressed only in leaves and
is cellularly localized in the chloroplasts and the
guard cells of stomata. Also included in this subfamily
is the fungal nuclear protein, Dot5p (for disrupter of
telomere silencing protein 5), which functions as an
alkyl-hydroperoxide reductase during post-diauxic
growth.

thiol specific antioxidant (TSA) protein also known as
TRX-dependent thiol peroxidase (Tpx). Tpx is a bacterial
periplasmic peroxidase which differs from other PRXs in
that it shows substrate specificity toward alkyl
hydroperoxides over hydrogen peroxide. As with all other
PRXs, the peroxidatic cysteine (N-terminal) of Tpx is
oxidized into a sulfenic acid intermediate upon reaction
with peroxides. Tpx is able to resolve this intermediate
by forming an intramolecular disulfide bond with a
conserved C-terminal cysteine (the resolving cysteine),
which can then be reduced by thioredoxin. This differs
from the typical 2-cys PRX which resolves the oxidized
cysteine by forming an intermolecular disulfide bond
with the resolving cysteine from the other subunit of
the homodimer. Atypical 2-cys PRX homodimers have a
loop-based interface (A-type for alternate), in contrast
with the B-type interface of typical 2-cys and 1-cys

This is the C-terminal domain of 1-Cys peroxiredoxin
(1-cysPrx), a member of the peroxiredoxin superfamily
which protect cells against membrane oxidation through
glutathione (GSH)-dependent reduction of phospholipid
hydroperoxides to corresponding alcohols. The C-terminal
domain is crucial for providing the extra cysteine
necessary for dimerisation of the whole molecule. Loss
of the enzyme's peroxidase activity is associated with
oxidation of the catalytic cysteine, upstream of this
domain; and glutathionylation, presumably through its
disruption of protein structure, facilitates access for
GSH, resulting in spontaneous reduction of the mixed
disulfide to the sulfhydryl and consequent activation of
the enzyme. The domain is associated with family
AhpC-TSA, pfam00578, which carries the catalytic
cysteine.

two subunits, COX I and COX II. It has been proposed
that Sco1 specifically delivers copper to the CuA site,
a dinuclear copper center, of the COX II subunit.
Mutations in human Sco1 and Sco2 cause fatal infantile
hepatoencephalomyopathy and cardioencephalomyopathy,
respectively. Both disorders are associated with severe
COX deficiency in affected tissues. More recently, it
has been argued that the redox sensitivity of the copper
binding properties of Sco1 implies that it participates
in signaling events rather than functioning as a

peroxisomes and the cytosol. The cellular location of
PRX5 suggests that it may have an important antioxidant
role in organelles that are major sources of reactive
oxygen species (ROS), as well as a role in the control
of signal transduction. PRX5 has been shown to reduce
hydrogen peroxide, alkyl hydroperoxides and
peroxynitrite. As with all other PRXs, the N-terminal
peroxidatic cysteine of PRX5 is oxidized into a sulfenic
acid intermediate upon reaction with peroxides. Human
PRX5 is able to resolve this intermediate by forming an
intramolecular disulfide bond with its C-terminal
cysteine (the resolving cysteine), which can then be
reduced by TRX, just like an atypical 2-cys PRX. This
resolving cysteine, however, is not conserved in other
members of the subfamily. In such cases, it is assumed
that the oxidized cysteine is directly resolved by an
external small-molecule or protein reductant, typical of
a 1-cys PRX. In the case of the H. influenza PRX5
hybrid, the resolving glutaredoxin domain is on the same
protein chain as PRX. PRX5 homodimers show an A-type

>gnl|CDD|216224 pfam00975, Thioesterase, Thioesterase domain. Peptide synthetases
are involved in the non-ribosomal synthesis of peptide
antibiotics. Next to the operons encoding these enzymes,
in almost all cases, are genes that encode proteins that
have similarity to the type II fatty acid thioesterases
of vertebrates. There are also modules within the
peptide synthetases that also share this similarity.
With respect to antibiotic production, thioesterases are
required for the addition of the last amino acid to the
peptide antibiotic, thereby forming a cyclic antibiotic.
Thioesterases (non-integrated) have molecular masses of
25-29 kDa.

>gnl|CDD|99895 cd05834, HDGF_related, The PWWP domain is an essential part of the
Hepatoma Derived Growth Factor (HDGF) family of
proteins, and is necessary for DNA binding by HDGF. This
family of endogenous nuclear-targeted mitogens includes
HRP (HDGF-related proteins 1, 2, 3, 4, or HPR1, HPR2,
HPR3, HPR4, respectively) and lens epithelium-derived
growth factor, LEDGF. Members of the HDGF family have
been linked to human diseases, and HDGF is a prognostic
factor in several types of cancer. The PWWP domain,
named for a conserved Pro-Trp-Trp-Pro motif, is a small
domain consisting of 100-150 amino acids. The PWWP
domain is found in numerous proteins that are involved
in cell division, growth and differentiation. Most
PWWP-domain proteins seem to be nuclear, often
DNA-binding, proteins that function as transcription
factors regulating a variety of developmental processes.

>gnl|CDD|132561 TIGR03522, GldA_ABC_ATP, gliding motility-associated ABC
transporter ATP-binding subunit GldA. Members of this
protein family are exclusive to the Bacteroidetes phylum
(previously Cytophaga-Flavobacteria-Bacteroides). GldA
is an ABC transporter ATP-binding protein (pfam00005)
linked to a type of rapid surface gliding motility found
in certain Bacteroidetes, such as Flavobacterium
johnsoniae and Cytophaga hutchinsonii. Knockouts of GldA
abolish the gliding phenotype. Gliding motility appears
closely linked to chitin utilization in the model
species Flavobacterium johnsoniae. Bacteroidetes with
members of this protein family appear to have all of the
genes associated with gliding motility.

likely that the PWWP domain acts as a site for
protein-protein binding interactions, influencing
chromatin remodeling and thereby regulating
transcriptional processes. Some PWWP-domain proteins
have been linked to cancer or other diseases; some are
known to function as growth factors.

>gnl|CDD|99712 cd05829, Sortase_E, Sortase E (SrtE) is a membrane transpeptidase
found in gram-positive bacteria that cleaves surface
proteins at a cell sorting motif and catalyzes a
transpeptidation reaction in which the surface protein
substrate is covalently linked to peptidoglycan for
display on the bacterial surface. Sortases are grouped
into different classes and subfamilies based on
sequence, membrane topology, genomic positioning, and
cleavage site preference. The function of Sortase E is
unknown. In two different sortase families, the
N-terminus either functions as both a signal peptide
for secretion and a stop-transfer signal for membrane
anchoring, or it contains a signal peptide only and the
C-terminus serves as a membrane anchor. Most
gram-positive bacteria contain more than one sortase
and it is thought that the different sortases anchor
different surface protein classes. The sortase domain
is a modified beta-barrel flanked by two (SrtA) or
three (SrtB) short alpha-helices.
