Biochem/physiol Actions

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.
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.

The growth pattern of Pseudomonas putida KT2440 in the presence of glucose and phenylacetic acid (PAA), where the sugar is used in preference to the aromatic compound, suggests that there is carbon catabolite repression (CCR) of PAA metabolism by glucose

In vivo, 2-keto-3-deoxy-6-phosphogluconate (KDPG) aldolase catalyzes the reversible, stereospecific retro-aldol cleavage of KDPG to pyruvate and D-glyceraldehyde-3-phosphate. The enzyme is a lysine-dependent (Class I) aldolase that functions through the intermediacy of a Schiff base. Here, we propose a mechanism for

Pseudomonas putida KT2440(pWW0) can use toluene via the TOL plasmid-encoded catabolic pathways and can use glucose via a series of three peripheral chromosome-encoded routes that convert glucose into 6-phosphogluconate (6PG), namely, the glucokinase pathway, in which glucose is transformed to

DeoR-type helix-turn-helix (HTH) domain proteins are transcriptional regulators of sugar and nucleoside metabolism in diverse bacteria and also occur in select archaea. In the model archaeon Haloferax volcanii, previous work implicated GlpR, a DeoR-type transcriptional regulator, in the transcriptional repression

The thermoacidophilic archaea Picrophilus torridus and Sulfolobus solfataricus catabolize glucose via a nonphosphorylative Entner-Doudoroff pathway and a branched Entner-Doudoroff pathway, respectively. Key enzymes for these Entner-Doudoroff pathways are the aldolases, 2-keto-3-deoxygluconate aldolase (KDG-aldolase) and 2-keto-3-deoxy-6-phosphogluconate aldolase [KD(P)G-aldolase]. KDG-aldolase from P.
