== Publication Abstract from PubMed ==
 +
A potential role in disulfide bond formation in the intracellular proteins of thermophilic organisms has recently been attributed to a new family of protein disulfide isomerase (PDI)-like proteins. Members of this family are characterized by a molecular mass of about 26kDa and by two Trx folds, each comprising a CXXC active site motif. We report on the functional and structural characterization of a new member of this family, which was isolated from the thermophilic bacterium Aquifex aeolicus (AaPDO). Functional studies have revealed the high catalytic efficiency of this enzyme in reducing, oxidizing and isomerizing disulfide bridges. Site-directed mutagenesis experiments have suggested that its two active sites have similar functional properties, i.e. that each of them imparts partial activity to the enzyme. This similarity was confirmed by the analysis of the enzyme crystal structure, which points to similar geometrical parameters and solvent accessibilities for the two active sites. The results demonstrated that AaPDO is the most PDI-like of all prokaryotic proteins so far known. Thus, further experimental studies on this enzyme are likely to provide important information on the eukaryotic homologue.
