Protein

Phospho-2-dehydro-3-deoxyheptonate aldolase

Gene

EC23916_3545

Organism
Escherichia coli 2.3916
Status
Unreviewed-Annotation score: -Protein inferred from homologyi

Functioni

Stereospecific condensation of phosphoenolpyruvate (PEP) and D-erythrose-4-phosphate (E4P) giving rise to 3-deoxy-D-arabino-heptulosonate-7-phosphate (DAHP).UniRule annotation

Catalytic activityi

Phosphoenolpyruvate + D-erythrose 4-phosphate + H2O = 3-deoxy-D-arabino-hept-2-ulosonate 7-phosphate + phosphate.UniRule annotation

Pathwayi: chorismate biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes chorismate from D-erythrose 4-phosphate and phosphoenolpyruvate.UniRule annotation
Proteins known to be involved in the 7 steps of the subpathway in this organism are:
  1. Phospho-2-dehydro-3-deoxyheptonate aldolase (EC23916_2510), Phospho-2-dehydro-3-deoxyheptonate aldolase (EC23916_0772), Phospho-2-dehydro-3-deoxyheptonate aldolase (EC23916_3545)
  2. 3-dehydroquinate synthase (aroB)
  3. 3-dehydroquinate dehydratase (aroD)
  4. Shikimate dehydrogenase (NADP(+)) (aroE), Quinate/shikimate dehydrogenase (ydiB)
  5. Shikimate kinase 1 (aroK), Shikimate kinase 2 (aroL)
  6. 3-phosphoshikimate 1-carboxyvinyltransferase (aroA)
  7. Chorismate synthase (aroC)
This subpathway is part of the pathway chorismate biosynthesis, which is itself part of Metabolic intermediate biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes chorismate from D-erythrose 4-phosphate and phosphoenolpyruvate, the pathway chorismate biosynthesis and in Metabolic intermediate biosynthesis.
