2-oxo-D-threo-4,5-dihydroxyadipate + H2O |
i.e. (2S,3R)-2,3-dihydroxy-5-oxohexanedioate. Product is the enantiomer of the product obtained in the reaction catalyzed by bifunctional L-talarate/galactarate dehydratase. When the GalrD-II-catalyzed reaction is performed in D2O, the proS hydrogen is replaced with deuterium, i.e., the acid that facilitates the departure of the OH group is likely the acid that catalyzes the formation of the alpha-oxo-beta-methylene product |
