>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|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|239315 cd03017, PRX_BCP, Peroxiredoxin (PRX) family, Bacterioferritin
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

>gnl|CDD|239316 cd03018, PRX_AhpE_like, Peroxiredoxin (PRX) family, AhpE-like
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
structure and sequence of AhpE, however, show greater
similarity to 2-cys PRXs than 1-cys PRXs. PRXs are
thiol-specific antioxidant (TSA) proteins that confer a
protective 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. The first step of
catalysis is the nucleophilic attack by the peroxidatic
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.

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.

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.

>gnl|CDD|239266 cd02968, SCO, SCO (an acronym for Synthesis of Cytochrome c
Oxidase) family; composed of proteins similar to Sco1, a
membrane-anchored protein possessing a soluble domain
with a TRX fold. Members of this family are required for
the proper assembly of cytochrome c oxidase (COX). They
contain a metal binding motif, typically CXXXC, which is
located in a flexible loop. COX, the terminal enzyme in
the respiratory chain, is imbedded in the inner
mitochondrial membrane of all eukaryotes and in the
plasma membrane of some prokaryotes. It is composed of
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
chaperone that transfers copper to COX II.

>gnl|CDD|239264 cd02966, TlpA_like_family, TlpA-like family; composed of TlpA,
ResA, DsbE and similar proteins. TlpA, ResA and DsbE are
bacterial protein disulfide reductases with important
roles in cytochrome maturation. They are
membrane-anchored proteins with a soluble TRX domain
containing a CXXC motif located in the periplasm. The
TRX domains of this family contain an insert,
approximately 25 residues in length, which correspond to
an extra alpha helix and a beta strand when compared
with TRX. TlpA catalyzes an essential reaction in the
biogenesis of cytochrome aa3, while ResA and DsbE are
essential proteins in cytochrome c maturation. Also
included in this family are proteins containing a
TlpA-like TRX domain with domain architectures similar
to E. coli DipZ protein, and the N-terminal TRX domain
of PilB protein from Neisseria which acts as a disulfide
reductase that can recylce methionine sulfoxide
reductases.
