Protein Sulfenic Acids in Redox Signaling

Annual Review of Pharmacology and Toxicology, 2004
Reactive (low pKa) cysteine residues in proteins are critical components in redox signaling. A particularly reactive and versatile reversibly oxidized form of cysteine, the sulfenic acid (Cys-SOH), has important roles as a catalytic center in enzymes and as a sensor of oxidative and nitrosative stress in enzymes and transcriptional regulators ...

The Redox Chemistry of Sulfenic Acids

Journal of the American Chemical Society, 2010
A persistent triptycenyl sulfenic acid is used as a model for cysteine-derived and other biologically relevant sulfenic acids in experiments which define their redox chemistry. EPR spectroscopy reveals that sulfinyl radicals are persistent and unreactive toward O(2), allowing the O-H bonding dissociation enthalpy (BDE) of the sulfenic acid to be ...

Formation and Repair of Papain Sulfenic Acid

Canadian Journal of Biochemistry, 1975
The inactivation of highly purified papain (2 × 10−5 M in distilled water) by hydrogen peroxide, generated by the γ-irradiation of water, was examined. The kinetics of activity loss at 23 °C was second order (k = 3.7 × 103 M−1 min−1) for papain:peroxide molar ratios of 1:1 or 2:1.

Capturing a Sulfenic Acid with Arylboronic Acids and Benzoxaborole

Journal of the American Chemical Society, 2013
Post-translational redox generation of cysteine-sulfenic acids (Cys-SOH) functions as an important reversible regulatory mechanism for many biological functions, such as signal transduction, balancing cellular redox states, catalysis, and gene transcription.

Garlic: Source of the Ultimate Antioxidants—Sulfenic Acids

Angewandte Chemie International Edition, 2008
ion of an allylic H atom. Clearly, allicin is not directly responsible for the inhibition of ML autoxidation; instead, an allicin decomposition product must be responsible. We also explored the effects of added hydrogen-bondacceptor (HBA) solvents on allicin-inhibited autoxidation reactions.

Discoveries in Sulfenic Acid Anion Chemistry

Phosphorus, Sulfur, and Silicon and the Related Elements, 2013
Abstract Sulfenates, the conjugate bases of sulfenic acids are nucleophilic species that can be alkylated at sulfur to create sulfoxides. Sulfenates are generally not isolable, but must be generated and functionalized in solution. In this report, we summarize accomplishments toward the liberation of 1-alkenesulfenate anions and also the first general ...
