Descripción

Biochem/physiol Actions

Metabolite in the pentose phosphate pathway, generating NADPH and pentoses; and in the in pentose and glucuronate interconversions; key intermediate in the Entner-Doudoroff pathway of some bacteria, substrate of 2-Keto-3-deoxy-6-phosphogluconate (KDPG) aldolase, catalyzing the reversible cleavage of KDPG to pyruvate and glyceraldehyde-3-phosphate. It was found to be the carbon catabolite repression signal of phenylacetic acid metabolism in P. putida KT2440. Expression from Pu was repressed mainly via PtsN in response to high levels of 2-dehydro-3-deoxygluconate-6-phosphate.

2-dehydro-3-deoxy-phosphogluconate is a substrate for the enzyme 2-dehydro-3-deoxy-phosphogluconate aldolase which converts it into D-glyceraldehyde 3-phosphate plus pyruvate.
