(2S,3S)-2,3-dicarboxyaziridine is a potent competitive inhibitor (Ki = 80 nM) of fumarase, an enzyme that catalyzes the hydration of fumaric acid to (S)-malic acid. Rationalize how (2S,3S)-2,3-dicarboxyaziridine might act as a competitive inhibitor of fumarase. Would you expect the enantiomer of the inhibitor to have a higher or lower Ki value? Explain.
