Function
Organic hydroperoxide resistance protein (OhrP) is a peroxidase involved in bacterial stress induced by organic hydroperoxides. OhrP requires dithiols for its activity[1]. For Xanthomonas campestris OhrR see OhrR.
Structural highlights
OhrP is endowed by a dithiol composed of a cysteine residue and a reactive cysteine residue (cysteinesulfonic acid) able to reduce peroxide[2].
