>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.

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

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,

>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.

tuberculosis AhpE. AhpE is described as a 1-cys PRX

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

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.

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.
