>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|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.

>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.

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

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.

PRX subfamily; composed of PRXs containing peroxidatic
and resolving cysteines, similar to the homodimeric
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
PRXs.

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.

>gnl|CDD|197870 smart00775, LNS2, This domain is found in Saccharomyces cerevisiae
protein SMP2, proteins with an N-terminal lipin domain
and phosphatidylinositol transfer proteins. SMP2 is
involved in plasmid maintenance and respiration. Lipin
proteins are involved in adipose tissue development and
insulin resistance.

>gnl|CDD|239268 cd02970, PRX_like2, Peroxiredoxin (PRX)-like 2 family; hypothetical
proteins that show sequence similarity to PRXs. Members
of this group contain a CXXC motif, similar to TRX. The
second cysteine in the motif corresponds to the
peroxidatic cysteine of PRX, however, these proteins do
not contain the other two residues of the catalytic
triad of PRX. PRXs 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 thioredoxin,
glutathione, trypanothione and AhpF. TRXs alter the
redox state of target proteins by catalyzing the
reduction of their disulfide bonds via the CXXC motif
using reducing equivalents derived from either NADPH or
ferredoxins.
