Gene

aroK

Organism
Burkholderia pseudomallei (strain 1710b)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Catalyzes the specific phosphorylation of the 3-hydroxyl group of shikimic acid using ATP as a cosubstrate.UniRule annotation

Catalytic activityi

ATP + shikimate = ADP + shikimate 3-phosphate.UniRule annotation

Cofactori

Mg2+UniRule annotationNote: Binds 1 Mg2+ ion per subunit.UniRule annotation

Pathwayi: chorismate biosynthesis

This protein is involved in step 5 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 (BURPS1710b_A0312)
  2. 3-dehydroquinate synthase (aroB)
  3. 3-dehydroquinate dehydratase (aroQ), 3-dehydroquinate dehydratase (aroQ)
  4. Shikimate dehydrogenase (NADP(+)) (aroE)
  5. Shikimate kinase (aroK)
  6. 3-phosphoshikimate 1-carboxyvinyltransferase (aroA), 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.
