3-hydroxypyruvate | an irreversible, time-dependent inhibitor, causes inactivation of mandelate racemase. Protection from inactivation by the competitive inhibitor benzohydroxamate. 3-Hydroxypyruvate undergoes Schiff-base formation with Lys166 at the active site, followed by formation of an aldehyde/enol(ate) adduct | Pseudomonas putida | |

evolution | mandelate racemase is a member of the enolase superfamily. The ability of the enzyme to form and deprotonate a Schiff-base intermediate furnishes a mechanistic link to other alpha/beta-barrel enzymes utilizing Schiff-base chemistry and is in accord with the sequence- and structure-based hypothesis that members of the metal-dependent enolase superfamily and the Schiff-base-forming N-acetylneuraminate lyase superfamily and aldolases share a common ancestor | Pseudomonas putida |
