DsbG, a Protein Disulfide Isomerase with Chaperone Activity [PDF]
DsbG, a protein disulfide isomerase present in the periplasm of Escherichia coli, is shown to function as a molecular chaperone. Stoichiometric amounts of DsbG are sufficient to prevent the thermal aggregation of two classical chaperone substrate proteins, citrate synthase and luciferase.

ERdj5 is the ER reductase that catalyzes the removal of non-native disulfides and correct folding of the LDL receptor [PDF]
ERdj5 is a member of the protein disulfide isomerase family of proteins localized to the endoplasmic reticulum (ER) of mammalian cells. To date, only a limited number of substrates for ERdj5 are known.

Conformational Resilience of Protein Disulfide Isomerase
Protein disulfide isomerase (PDI) is a 57 kDa protein with both oxidoreductase and chaperone activities that is mainly localized to the endoplasmic reticulum. It is a U‐shaped protein with an abb'xa’ structural organization where the a and a′ domains have conserved CGHC active sites, the b and b′ domains are involved with substrate binding, and x is an

Identification of Protein-disulfide Isomerase Activity in Fibronectin [PDF]
Assembly and degradation of fibronectin-containing extracellular matrices are dynamic processes that are up-regulated during wound healing, embryogenesis, and metastasis. Although several of the early steps leading to fibronectin deposition have been identified, the mechanisms leading to the accumulation of fibronectin in disulfide-stabilized multimers

Cytosolic thioredoxin reductase 1 is required for correct disulfide formation in the ER [PDF]
Folding of proteins entering the secretory pathway in mammalian cells frequently requires the insertion of disulfide bonds. Disulfide insertion can result in covalent linkages found in the native structure as well as those that are not, so‐called non ...

Mitochondrial Thioredoxin System as a Modulator of Cyclophilin D Redox State [PDF]
The mitochondrial thioredoxin system (NADPH, thioredoxin reductase, thioredoxin) is a major redox regulator. Here we have investigated the redox correlation between this system and the mitochondrial enzyme cyclophilin D.

Multiple protein disulfide isomerases support thrombosis [PDF]
Purpose of review The present review provides an overview of recent findings on new members of the protein disulfide isomerase (PDI) family required for thrombosis. Recent findings Twenty years ago PDI was shown to mediate platelet aggregation, and 10 years ago PDI was shown to ...
