Disulfide Bonds and Protein Structure: Proteins have various levels of structural organization. Primary structure is the sequence of amino acids making up the protein. Secondary structure is whether the protein forms α-helices or β-sheet structures. The tertiary structure is how the combination of ...
In basic terms a disulfide bond within a protein represents a covalent linkage between the sulfur atoms of two cysteine residues. This linkage plays a fundamental role in protein biochemistry through the regulation of protein structure and function. The formation of disulfide bonds is favored in the...
This experiment was the first to show that a protein could fold into its correct tertiary structure with only the information provided in its amino acid sequence. Anfinsen and colleagues were also the first to note a potential caveat to their discovery. Although correct formation of RNase A鈥檚...

U.v. circular dichroic spectral measurements revealed that the increase in the conformational flexibility (up to 15 S-S bond cleavage) results from a decrease in both secondary (ordered) and tertiary structure of the protein. These measurements also indicated that the decrease in the conformational...
The applications of disulfide-bond chemistry to studies of protein folding, structure, and stability are reviewed and illustrated with bovine pancreatic ribonuclease A (RNase A). After surveying the general properties and advantages of d... WJ Wedemeyer,E Welker,M Narayan,... - 《Biochemistry》 ...
In the formation of protein tertiary structure, disulfide bonds play a central role2,6,7. The activity of many natural products and drugs depends on the exchange reaction of disulfide bonds in proteins4,8,9. The lipoic acid present in the mitochondria can increase the synthesis of ATP in ...
(Supplementary Figure2). We envisioned that this intra-subunit disulfide bond could play an important role in maintaining the tertiary structure of the Hαsubunit, thereby stabilizing the quaternary structure of NF-8. To test this idea, we planned to delete this intra disulfide bond by genetic ...
LEPTIN protein tertiary structure was downloaded from Protein Data Bank (PDB) (http://www.rcsb.org/pdb) with the entry (1AX8) and examined to remove water molecules. In order to find potential mutation sites to form disulfide bonds, Disulfide by Design server [31] was used. Based on the...
