If a protein is composed of the two polypeptide chains connected together via two disulfide bonds with no free sulfhydryl groups. The protein was treated with mercaptoethanol to break its disulfide bonds, and then the mercaptoethanol was removed so that disulfide bonds could re-form. How many different arrangements of disulfide bonds are possible? (the protein has a total of 4 Cys and 2-bonds)
Please, explain your answer in detail.
