Disulfide bond formation A protein, shown schematically in Figure 6.30, may contain several cysteines (represented as light colored balis), which may pair together to form disulfide bonds. For six cysteines, three disulfide bonds can form; the figure shows the pairing arrangement 1-6,2-5,3-4 . How many different disulfide pairing arrangements are possible? Derive the general formula for the number of different pairing arrangements when there are n cysteines (and n is even). (Adapted from problem

The combinatorics of disulfide bond formation. A protein may contain several cysteines, which may pair together to form disulfide bonds as shown in Figure 1.18. If there is an even number n of cysteines, n / 2 disulfide bonds can form. How many different disulfide pairing arrangements are possible? | Numerade

Which amino acids can form a disulfide bond? - TimesMojo

SOLVED: Secondary structures are stabilized by disulfide bridges; hydrogen bonds; and covalent bonds between adjacent amino acids. These interactions occur in the polypeptide backbone and between different protein subunits. Additionally, hydrogen bonds are responsible for joining adjacent nucleotides on a DNA strand.
