Question

A potential enzyme inhibitor was designed to mimic the transtition state. What kind of inhibitor is it, and how can its effectiveness be tested? Please explain the reasoning for the answer

A) Competitive inhibitor, test by running activity assays +/- inhibitor and measure changes in Vmax

B) Competitive inhibitor, test by running activity assays +/- inhibitor and measure changes in Km

C) Non-competitive inhibitor, test by running activity assays +/- inhibitor and measure changes in Vmax

D) Non-competitive inhibotr, test by running activity assays +/- inhibitor and measure changes in Km

Explanation / Answer

Option b is correct because inhibitor bind at active site, its effectiveness is tested by measure change in Km because a competitive inhibitor will raise the Km value for its substrate with no change in Vmax value.
