Summary:
The Entner-Doudoroff pathway joins the pentose phosphate pathway (oxidative branch) I to glycolysis via two steps, catalyzed by inducible enzymes.

This pathway is important to Escherichia coli because sugar acids, which are significant nutrients in both of its habitats, intestinal and aquatic, are metabolized via this pathway. Strains that are mutationally blocked in this pathway are unable to grow on gluconate, glucuronate, or galacturonate and are also unable to colonize the mouse intestine [Sweeney96]. The uronic acids feed into the pathway's sole intermediate, 2-keto-3-deoxy-6-phospho-gluconate so the dependence of their metabolism on an intact Entner-Doudoroff pathway is clear [Peekhaus98a]. The dependence of gluconate's metabolism on an intact Entner-Doudoroff pathway is less obvious because it is also metabolized via the pentose phosphate pathway.

Enzymes of the Entner-Doudoroff pathway are induced by growth on gluconate, glucuronate, or methyl-β-D-glucuronide; phosphate or carbon limitation [Murray05].

Superpathways: superpathway of glycolysis and Entner-Doudoroff

Variants: Entner-Doudoroff pathway II (non-phosphorylative) , Entner-Doudoroff pathway III (semi-phosphorylative)
