I agree, for example Pepsin[1] that is the protein inside the stomach that split proteins has Cysteine [2] > Pepsin forms three between the sulfur atoms of cysteine residues in the peptide chain which hold important roles in the folding of the protein and stabilizing the two domains [1] https://en.wikipedia.org/wiki/Pepsin https://en.wikipedia.org/wiki/Pepsin [2] https://biology.kenyon.edu/BMB/jsmol2021/Cat_Marko/index.htm#:~:text=Pepsin%20forms%20three,the%20two%20domains https://biology.kenyon.edu/BMB/jsmol2021/Cat_Marko/index.htm...
