REACTION DIAGRAM
oxaloacetate + H2O
-
mechanism in which Lys 184 initiates the reaction by abstraction of the R-proton to generate a Mg2+-stabilized enediolate intermediate, and the vinylogous beta-elimination of the 3-OH group is general acid-catalyzed by the His 322, accomplishing the anti-elimination of water. The replacement of the leaving group by solvent-derived hydrogen is stereorandom
