How are disulfide bonds formed
WebDisulfide bonds also play a significant role in the vulcanization of rubber. In eukaryotes. In eukaryotic cells, disulfide bonds are generally formed in the lumen of the RER (rough endoplasmic reticulum) but not in the cytosol. This is due to the oxidative environment of the ER and the reducing environment of the cytosol (see glutathione). WebThis is because the disulfide bonds (established during the initial folding of the protein, during its synthesis), reduce the number of possible ways to "misfold". Quaternary Structure In nature, some proteins are formed from multiple proteins, also known as subunits, and the interaction of these subunits forms the quaternary structure .

WebTheoretically, there is generation of a free -SH upon covalent modification of a protein that may eventually form disulfide bonds with another polypeptide creating a cross-linked oligomer. We have, therefore, treated the oligomers formed on day 6 with DTT and examined the oligomeric status by measuring light scattering intensity (Fig. 4).
