Cysteine disulfide bonds aggregation
WebNov 19, 2024 · A disulfide bond, however, is a strong covalent bond formed between sulfur atoms of two cysteine amino acids. Due to its high bonding energy, disulfide bonds can greatly enhance protein’s tolerance to extreme environments such as heat and acidity and can be found vastly in enzymes of thermophilic species [ 17 , 18 , 19 ]. WebSep 12, 2024 · Disulfide bridges, covalent bonds formed between two cysteine residues, further reinforce the shape of a protein. Disulfide bridges form when the sulfhydryl groups of two cysteine residues come into close contact because of protein folding. Covalent bonds are not a weak interaction.
