?
2-dehydro-3-deoxy-D-galactonate
the enzyme shows substrate promiscuity, as measured in the direction of aldol synthesis. The enzyme catalyzes the formation of both 2-dehydro-3-deoxy-D-gluconate and its C-4 epimer 2-keto-3-deoxygalactonate from D- or L-glyceraldehyde and pyruvate at a similar ratio, indicating lack of stereospecific control in formation and cleavage of 2-dehydro-3-deoxy-D-gluconate and 2-dehydro-3-deoxy-D-galactonate
