Many enzymes are irreversibly inhibited by heavy metal ions such as Hg2+, Cu²+, or Agt, which can react with essential sulfhydryl groups to form mercaptides. Enz-SH+ Ag+ Enz-S-Ag + H+ The affinity of Ag for sulfhydryl groups is so great that Agt can be used to titrate-SH groups quantitatively. An investigator added just enough AgNO, to completely inactivate a 10.0 mL solution containing 1.0 mg/ml. enzyme. A total of 0.342 μmol of AgNO, was required. Calculate the minimum molecular weight of the enzyme minimum molecular weight: enzyme. 5.7 X104 Incorrect g/mol
