: 2-dehydro-3-deoxy-D-gluconate degradation Pathwayi
This protein is involved in step 1 of the subpathway that synthesizes D-glyceraldehyde 3-phosphate and pyruvate from 2-dehydro-3-deoxy-D-gluconate. 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.
