Peroxiredoxins (Prxs), some of nature's dominant peroxidases, use a conserved Cys residue
to reduce peroxides. They are highly expressed in organisms from all kingdoms, and in …

Peroxiredoxins (Prxs) are ubiquitous proteins that use an active site Cys residue to reduce
hydroperoxides. Structural studies since the first Prx structure was determined in 1998 have …

To reduce peroxides, peroxiredoxins (Prxs) require a key “peroxidatic” Cys that, in a
substrate-ready fully folded (FF) conformation, is oxidized to sulfenic acid and then, after a …

MATERIALS AND METHODS Protein Samples—Samples of [U-15N] Prx, C76A [U-15N] Prx,
and U-15N, 13C, 50%[2H] Prx were produced as previously described (19). Populus tremula …

Background Oxygenic photosynthesis is accompanied by the formation of reactive oxygen
species (ROS), which damage proteins, lipids, DNA and finally limit plant yield. The …

Peroxiredoxins (Prx) make up a family of enzymes that reduce peroxides using a peroxidatic
cysteine residue; among these, members of the PrxQ subfamily are proposed to be the most …

Considerable insights into the oxidoreduction activity of the Xanthomonas campestris
bacterioferritin comigratory protein (XcBCP) have been obtained from trapped …

The Anabaena sp.(ANASP) genome contains seven open reading frames with homology to
thiol peroxidase (TPx), also known as peroxiredoxin (Prx). Based on sequence similarities …

Peroxiredoxin systems in plants were demonstrated involved in crucial roles related to
reactive oxygenated species (ROS) metabolism and the linked cell signalling to ROS …

Bcps constitute a group of antioxidant enzymes, belonging to the Prx family, that are widely
distributed in bacteria, plants, and fungi. These proteins can contain two conserved …
