19-159 3.65e-78

Peroxiredoxin (PRX) family, Atypical 2-cys 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.

24-159 4.42e-41

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.

19-159 9.57e-30

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.

22-154 6.22e-15

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 telomere silencing protein 5), which functions as an alkyl-hydroperoxide reductase during post-diauxic growth.

20-144 1.43e-11

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.
