Catalysis of Disulfide Isomerization in Thrombospondin 1 by Protein Disulfide Isomerase
Biochemistry, 1996Thrombospondin 1 is a multidomain glycoprotein from platelets and most cells that participates in diverse biological processes. The structure and some functional properties of thrombospondin 1 are regulated by disulfide interchange in the Ca(2+)-binding repeats and C-globular domain. The recent identification of the enzyme, protein disulfide isomerase,

Mechanistic insights into a copper–disulfide interaction in oxidation of imines by disulfides
Chemical Communications, 2009The concept of using disulfides as an oxidant for Cu(i) is introduced as part of a Cu-catalyzed process leading to the formation of benzothiazole from an iminodisulfide under an inert atmosphere.

Anodic Oxidation of Disulfides: Detection and Reactions of Disulfide Radical Cations
The Journal of Organic Chemistry, 2013The anodic oxidation of five diaryldisulfides have been studied in a dichloromethane/[NBu4][B(C6F5)4] electrolyte. Cyclic voltammetry scans of (p-RC6H4)2S2 (R = Me, 1a; R = F, 1b; R = OMe, 1c) show modest chemical reversibility for the 1(0/+) couple (E1/2 values vs ferrocene: 1.04 V for 1a, 1.21 V for 1b, 0.92 V for 1c), providing the first ...

Chemical reduction of disulfides
1987Publisher Summary This chapter discusses the chemical reduction of disulfides. Disulfides are easily and specifically reduced by thiols, which are the most used reagents for this purpose. However, the excess of the thiol used as a reductant has to be removed before it is possible to assay the newly generated SH groups.

Formation and isomerization of disulfide bonds in proteins: Protein disulfide-isomerase
1984Publisher Summary Protein disulfide-isomerase (PDI) catalyzes the formation of native proteins from the reduced denatured state. When incubated in the presence of a thiol compound, PDI catalyzes the regain of native ribonuclease structure from the scrambled ribonuclease, with concomitant return of activity toward RNA.

Electrochemical reduction of disulfides
1987Publisher Summary Electrochemical reduction of disulfides has been reported to give higher yields of thiols than alternative zinc-acid or borohydride reductions. The use of electrochemical reduction is exemplified by the low toxicity, high yield, selective analysis of urinary captopril [(S,S)-l-(3-mercapto-2-D-methyl-l-oxopropyl)-L-proline], an ...

Theoretical prediction of disulfide defects (S22−) in molybdenum disulfide monolayers
Journal of Molecular ModelingDefects have a noticeable influence on many properties of two-dimensional materials. The controlled formation of defects can be used for fine-tuning the electronic and chemical properties of transition metal dichalcogenide monolayers. The formation of a new type of displacement defect on the molybdenum disulfide (MoS2) monolayer surface has been ...
