WebHere we use site-specific mutagenesis and two-dimensional NMR of l-[3-(13)C]cysteine-labeled proteins to determine the redox state of the individual cysteines in HO-2 and assess their roles in binding of heme. The results indicate that in the apoprotein, Cys(282) and Cys(265) are in the oxidized state, probably in an intramolecular disulfide bond. WebDec 27, 2024 · The disulfide bond in these enzymes may not affect their structural stability. In contrast, if the six cysteine residues of rAlgSV1-PL7 form intramolecular disulfide bonds, they regulate the conformation of the enzyme and may contribute to the observed long-lived enzyme activity.

WebApr 11, 2024 · The unique feature of cysteine residues is their ability to form reversible, covalent intramolecular, and intermolecular disulfide bonds through their thiol side chains. Disulfide bonds are also one of the most common post-translational modifications that occur during oxidative folding. WebIntramolecular bonding. There are several types of bonding inside molecules (intramolecular bonds) and between molecules (intermolecular bonds).
