Protein disulfide bond formation is a rate limiting step in protein, folding and is catalyzed by enzymes belonging to the protein disulfide, oxidoreductase superfamily, including protein disulfide isomerase (PDI) in, eucarya and DsbA in bacteria. The first high resolution X-ray crystal, structure of a protein disulfide oxidoreductase from the hyperthermophilic, archaeon Pyrococcus furiosus reveals structural details that suggest a, relation to eukaryotic PDI. The protein consists of two homologous, structural units with low sequence identity. Each unit contains a, thioredoxin fold with a distinct CXXC active site motif. The, accessibilities of both active sites are rather different as are, very, likely, their redox properties. The protein shows the ability to catalyze, the oxidation of dithiols as well as the reduction of disulfide bridges.
