Miscellaneousi

Miscellaneous

Reaction mechanism is a simple extension of the two-step reaction catalyzed by other members of the family: Lys-184 initiates the reaction by abstraction of the alpha-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 stereo-random, suggesting that the enol tautomer of oxaloacetate is the product (PubMed:17144653).1 Publication
