ID 2.3.1.333 DE 3-oxoglutarate synthase. CA 2 malonyl-CoA + H2O = 3-oxoglutarate + CO2 + 2 CoA. CC -!- The enzyme has been isolated from the plants Erythroxylum CC novogranatense and Atropa belladonna, and is widely distributed in CC Solanaceae and Erythroxylaceae plants, where it is involved in the CC biosynthesis of tropane alkaloids. CC -!- The enzyme has also been isolated from the club-moss Huperzia CC serrata, and by implication is likely present in other Lycopodiaceae CC plants, where it is involved in the biosynthesis of lycopodium CC alkaloids.
