Functioni

Catalytic activityi

4-hydroxy-2-oxoglutarate = pyruvate + glyoxylate.
2-dehydro-3-deoxy-6-phosphate-D-gluconate = pyruvate + D-glyceraldehyde 3-phosphate.

Pathway:i2-dehydro-3-deoxy-D-gluconate degradation

This protein is involved in step 2 of the subpathway that synthesizes D-glyceraldehyde 3-phosphate and pyruvate from 2-dehydro-3-deoxy-D-gluconate.
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. 2-dehydro-3-deoxygluconokinase (kdgK)
  2. Putative KHG/KDPG aldolase (eda)
This subpathway is part of the pathway 2-dehydro-3-deoxy-D-gluconate degradation, which is itself part of Carbohydrate acid metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes D-glyceraldehyde 3-phosphate and pyruvate from 2-dehydro-3-deoxy-D-gluconate, the pathway 2-dehydro-3-deoxy-D-gluconate degradation and in Carbohydrate acid metabolism.
