Properties of the thioredoxin fold superfamily are modulated by a single amino acid residue [PDF]
The ubiquitous thioredoxin fold proteins catalyze oxidation, reduction, or disulfide exchange reactions depending on their redox properties. They also play vital roles in protein folding, redox control, and disease.

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.

Cancer stem cells (CSCs) are a great challenge in the fight against cancer because these self-renewing tumorigenic cell fractions are thought to be responsible for metastasis dissemination and cases of tumor recurrence. In comparison with non-stem cancer

Biophysical characterization of Cyclophilin B reveals membrane localization as its primary functional determinant as a prolyl isomerase. [PDF]
Abstract The endoplasmic reticulum (ER) provides a specialized environment for the folding of secreted and membrane proteins, a process supported by many different chaperones. Among these chaperones, peptidyl‐prolyl cis/trans isomerases (PPIases) catalyze a rate‐limiting conformational step in protein folding, yet the principles governing isoform ...

Inhibition of Protein Disulfide Isomerase in Thrombosis [PDF]
AbstractThis MiniReview addresses our current understanding of the mechanisms by which protein disulfide isomerase (PDI) mediates thrombus formation and discusses the potential of blocking thrombosis by targeting PDI. Thiol isomerases are ubiquitous oxidoreductases primarily localized to the endoplasmic reticulum (ER) where they serve a critical role ...

Protein Disulfide Isomerase and Host-Pathogen Interaction [PDF]
Reactive oxygen species (ROS) production by immunological cells is known to cause damage to pathogens. Increasing evidence accumulated in the last decade has shown, however, that ROS (and redox signals) functionally regulate different cellular pathways in the host-pathogen interaction.

Introduction to protein folding for physicists [PDF]
The prediction of the three-dimensional native structure of proteins from the knowledge of their amino acid sequence, known as the protein folding problem, is one of the most important yet unsolved issues of modern science.

Protein disulfide-isomerase interacts with a substrate protein at all stages along its folding pathway [PDF]
In contrast to molecular chaperones that couple protein folding to ATP hydrolysis, protein disulfide-isomerase (PDI) catalyzes protein folding coupled to formation of disulfide bonds (oxidative folding).

Interaction of Calreticulin with Protein Disulfide Isomerase [PDF]
We report here that calreticulin interacts with protein disulfide isomerase (PDI). The PDI-calreticulin complex can be dissociated by Zn(2+)-iminodiacetate-substituted Sepharose-agarose chromatography, suggesting that these interactions may be Zn2+-dependent.

Folding of a single domain protein entering the endoplasmic reticulum precedes disulfide formation [PDF]
The relationship between protein synthesis, folding and disulfide formation within the endoplasmic reticulum (ER) is poorly understood. Previous studies have suggested pre-existing disulfide links are absolutely required to allow protein folding and ...
