Quantification of thiols and disulfides [PDF]

open access: yesBiochimica et Biophysica Acta (BBA) - General Subjects, 2014
Disulfide bond formation is a key posttranslational modification, with implications for structure, function and stability of numerous proteins. While disulfide bond formation is a necessary and essential process for many proteins, it is deleterious and disruptive for others.

Thiol/Disulfide homeostasis in patients with rheumatoid arthritis

open access: yesRomanian Journal of Internal Medicine, 2019
Background. Oxidative stress may play an important role in rheumatoid arthritis (RA) etiopathogenesis. The thiol group is a very strong antioxidant. In this study, we aimed to investigate the presence of oxidative stress in patients with RA by evaluating

Thiol-disulfide oxidoreductases: assays, inhibitors, and metabolic roles

open access: yes, 2022
Thorpe, ColinDisulfide bonds are common post-translational modifications which serve to stabilize or impart function onto proteins. Although this product of oxidation between two cysteine thiols is relatively stable, disulfide bonds are able to undergo ...

Identification of Sulfenylated Cysteines in Arabidopsis thaliana Proteins Using a Disulfide-Linked Peptide Reporter

open access: yesFrontiers in Plant Science, 2020
In proteins, hydrogen peroxide (H2O2) reacts with redox-sensitive cysteines to form cysteine sulfenic acid, also known as S-sulfenylation. These cysteine oxidation events can steer diverse cellular processes by altering protein interactions, trafficking,

Disulfide-Bridged (Mo3S11) Cluster Polymer: Molecular Dynamics and Application as Electrode Material for a Rechargeable Magnesium Battery

open access: yes, 2016
Exploring novel electrode materials is critical for the development of a next-generation rechargeable magnesium battery with high volumetric capacity. Here, we showed that a distinct amorphous molybdenum sulfide, being a coordination polymer of disulfide-

Redox-Click Chemistry for Disulfide Formation from Thiols

open access: yes, 2023
The dynamic disulfide linkage plays a vital role in various biological processes as well as drugs and biomaterials. Oxidation of thiols is a widely utilized approach for disulfide synthesis; however, achieving both optimal reactivity and selectivity ...

Characterisation of the oxidoreductase Erol-Lß and the misfolding of the secretory pathway substrate HLA-B27 [PDF]

open access: yes, 2007
The endoplasmic reticulum (ER) is the site of oxidative folding for proteins entering the secretory pathway. Here, nascent polypeptides acquire disulfide bonds, which confer both stability and functionality on secretory and ER-resident proteins.

Disulfide-Cross-Linked Tetra-PEG Gels

open access: yes
The preparation of polymer gels via cross-linking of four-arm star-shaped poly­(ethylene glycol) (Tetra-PEG) precursors is an attractive strategy to prepare networks with relatively well-defined topologies. Typically, Tetra-PEG gels are obtained by cross-

Top-Down Mass Spectrometry and Assigning Internal Fragments for Determining Disulfide Bond Positions in Proteins

open access: yes, 2022
Disulfide bonds in proteins have a substantial impact on protein structure, stability, and biological activity. Localizing disulfide bonds is critical for understanding protein folding and higher-order structure.

Redox-Sensitive Linear and Cross-Linked Cystamine-Based Polymers for Colon-Targeted Drug Delivery: Design, Synthesis, and Characterisation

open access: yesPharmaceutics, 2020
Cystamine-based polymers may help to achieve controlled and targeted drug delivery to the colon due to their susceptibility to breakage of the disulfide linkage in the low redox potential environment of the colon.
