WebInteraction between cysteine side chains forms disulfide linkages in the presence of oxygen, the only covalent bond that forms during protein folding. Figure 3.29 A variety of chemical interactions determine the proteins' tertiary structure. WebWhen a solution of a protein is boiled, the protein frequently becomes insoluble—i.e., it is denatured—and remains insoluble even when the solution is cooled. The denaturation of the proteins of egg white by heat—as when boiling an egg—is an example of irreversible denaturation. The denatured protein has the same primary structure as the original, or …
WebJul 27, 2024 · Conversely, in the case of the constant domain (C L) of the antibody light chain (Figure 1.1.2), formation of its single disulfide bond accelerated folding up to ∼100-fold. 68,69 In this case, the disulfide bond is found in the hydrophobic core of the protein and is part of the immunoglobulin folding nucleus. 70,71 For other proteins that ... WebOne very important and very strong tertiary structure bond is a covalent bond that occurs between R groups on cysteine residues. These R-groups contain sulfur, which can interact with other sulfurs to form a disulfide bridge. The loss of a protein’s 3-dimensional shape is called denaturing the protein.
