Consider the following mechanism for an enzyme-catalyzed peptide hydrolysis reaction. The black line outlines the enzyme active site. Aspi H-O Enzyme Aspil Aspi O O OH O-H O Aspu Aspi OH H₂N- H-O Aspl
Which one of the following statements about this mechanism is FALSE? A) Asp, may be able to contribute to catalysis by hydrogen bonding with Asp₁| and so help to position the general acid/base group. B) The reaction involves formation of a tetrahedral carbon oxyanion. C) The reaction involves formation of a ternary complex. D) Asp acts first as an acid and then as a base.
