Enz-SH + Ag* - Enz-S-Ag + H* The affinity of Ag* for sulfhydryl groups is so great that Ag* can be used to titrate -SH groups quantitatively. To 10.0 mL of a solution containing 3.5 mg/mL of a pure enzyme, an investigator added just enough AGNO, to completely inactivate the enzyme. A total of 0.536 umol AGNO, was required. Calculate the minimum molecular weight (M,) of the enzyme. minimum M, = The determined M, is not exact, but it is a minimum value for the M, of the enzyme. Why does the M, value obtained this way give only the minimum molecular weight? There is only one polypeptide chain. There are no disulfide bonds in the protein. There is only one titratable -SH group per protein molecule. The Ag* would also react with the terminal carboxyl group.
