Thiol–Disulfide Exchange in Signaling: Disulfide Bonds As a Switch
Antioxidants & Redox Signaling, 2013The major function of disulfide bonds is not only the stabilization of protein structures. Over the last 30 years, a change in perspective took place driven by groundbreaking experiments, which promoted disulfide bonds to central players in essential thiol-disulfide exchange reactions involved in signal transduction, thiol protection, and redox ...

Dicubyl disulfide (1) has been prepared in six steps from commercially available dimethyl-1,4-cubanedicarboxylate in 47% overall yield. In the final step, the previously unknown cubanethiol 2 was oxidized to disulfide 1. X-ray crystallography for 1 reveals the shortest tetragonal C-S bond on record (1.771 A).

Cleavage of disulfide polymers. III. By disulfides
Journal of Applied Polymer Science, 1964AbstractA study was made of the cleavage of polymeric disulfide by organic disulfides of different structures in the presence and absence of sodium disulfide. While aliphatic disulfides will cleave polymeric disulfides only in the presence of sodium disulfide, hydroxyethyl disulfide and aromatic disulfides will cause partial cleavage in the absence of ...

Disulfide luminescence. Emission characteristics of cyclic tetrapeptide disulfides
Biochemical and Biophysical Research Communications, 1981Luminescence has been detected in cyclic tetrapeptide disulfides containing only nonaromatic residues. Excitation of the S-S- n-cr transition between 280 and 290 nm leads to.ernission in the region 300-340 nm. The position and intensity of the emission band depends on the stereochemistry of the peptide and polarity of the solvent. Quantum yields

Disulfide-disulfide interchange catalyzed by a liver supernatant enzyme
Biochimica et Biophysica Acta (BBA) - Enzymology, 1979An enzyme widely distributed in rabbit tissues which catalyzes an interchange between N,N-di-dinitrophenyl-L-cystine and oxidized glutathione to form the mixed disulfide is described. D-Penicillamine disulfide can be substituted for oxidized glutathione and the mixed disulfide of cysteine and glutathione can serve as the sole substrate giving as one ...

Disulfide Bond in Diethyl Disulfide: A Rotational Spectroscopic Study
The Journal of Physical Chemistry A, 2018Diethyl disulfide was investigated by pulsed jet Fourier transform microwave spectroscopy. The spectroscopic study was complemented by ab initio calculations. The first two most stable conformers predicted at the MP2/6-311++G(d,p) level of theory were observed in the supersonic expansion. Two 13C and one 34S isotopologues for the most stable conformer (

Thermal properties of some cyclic disulfides: naphthalene disulfide and diphenylene disulfide
Thermochimica Acta, 1975Abstract The specific heat, the melting heat and entropy, the vaporization heat of naphtalene disulfide (C10H6S2) and of diphenylene disulfide (C12H8S2) have been determined by differential scanning calorimetry (DSC). Over the temperature range examined the specific heat may be represented as follows: where T is the temperature in degrees Kelvin,

To find their potential use in protein research, direct addition of a disulfide compound to alkyne (namely disulfide-yne reaction) and S-arylation with arenediazonium salt (namely disulfide-diazonium reaction) were investigated in aqueous or protic solutions.

Biochemistry, 2006
Disulfide bonds have been generally considered to be either structural or catalytic. Structural bonds stabilize a protein, while catalytic bonds mediate thiol-disulfide interchange reactions in substrate proteins. There is emerging evidence for a third type of disulfide bond that can control protein function by triggering a conformational change when ...
