OXIDIZED AND REDUCED FORMS OF HUMAN PEROXIREDOXIN 5OXIDIZED AND REDUCED FORMS OF HUMAN PEROXIREDOXIN 5
Structural highlights
Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedPeroxiredoxin 5 (PRDX5) belongs to the PRDX superfamily of thiol-dependent peroxidases able to reduce hydrogen peroxide, alkyl hydroperoxides and peroxynitrite. PRDX5 is classified in the atypical 2-Cys subfamily of PRDXs. In this subfamily, the oxidized form of the enzyme is characterized by the presence of an intramolecular disulfide bridge between the peroxidatic and the resolving cysteine residues. We report here three crystal forms in which this intramolecular disulfide bond is indeed observed. The structures are characterized by the expected local unfolding of the peroxidatic loop, but also by the unfolding of the resolving loop. A new type of interface between PRDX molecules is described. The three crystal forms were not oxidized in the same way and the influence of the oxidizing conditions is discussed. The crystal structures of oxidized forms of human peroxiredoxin 5 with an intramolecular disulfide bond confirm the proposed enzymatic mechanism for atypical 2-Cys peroxiredoxins.,Smeets A, Marchand C, Linard D, Knoops B, Declercq JP Arch Biochem Biophys. 2008 Sep 1;477(1):98-104.
