WebNational Center for Biotechnology Information Thiolates, not thiols, attack disulfide bonds. Hence, thiol–disulfide exchange is inhibited at low pH (typically, below 8) where the protonated thiol form is favored relative to the deprotonated thiolate form. (The pK a of a typical thiol group is roughly 8.3, but can vary due to its environment.). Thiol–disulfide … See more In biochemistry, a disulfide (or disulphide in British English) refers to a functional group with the structure R−S−S−R′. The linkage is also called an SS-bond or sometimes a disulfide bridge and is usually derived by the coupling of two See more Symmetrical disulfides are compounds of the formula R2S2. Most disulfides encountered in organo sulfur chemistry are symmetrical disulfides. Unsymmetrical disulfides (also called heterodisulfides) are compounds of the formula RSSR'. They are less common in … See more Thiosulfoxides are orthogonally isomeric with disulfides, having the second sulfur branching from the first and not partaking in a continuous … See more Rubber manufacturing The vulcanization of rubber results in crosslinking groups which consist of disulfide (and … See more Occurrence in proteins Disulfide bonds can be formed under oxidising conditions and play an important role in the folding … See more The disulfide anion is S 2, or S−S . In disulfide, sulfur exists in the reduced state with oxidation number −1. Its electron configuration then resembles that of a chlorine atom. It thus tends to form a covalent bond with another S center to form S 2 group, … See more • Sela, M.; Lifson, S. (1959). "The reformation of disulfide bridges in proteins".

WebNov 11, 2003 · DsbA is a 21-kDa periplasmic protein that is a member of the thioredoxin superfamily. DsbA has a very reactive active-site high-redox-potential disulfide that can readily transfer oxidizing equivalents to a wide variety of substrate proteins (1, 2).When DsbA donates its disulfide bond to a secreted target protein, DsbA is released in a … WebKeywords: disulfide bonds, pH-triggered charge-reversal, redox sensitive, chitosan oligosaccharide, human cervical carcinoma therapy.
