Functioni

Catalyzes the anti-1,4-elimination of the C-3 phosphate and the C-6 proR hydrogen from 5-enolpyruvylshikimate-3-phosphate (EPSP) to yield chorismate, which is the branch point compound that serves as the starting substrate for the three terminal pathways of aromatic amino acid biosynthesis. This reaction introduces a second double bond into the aromatic ring system.UniRule annotation

Catalytic activityi

5-O-(1-carboxyvinyl)-3-phosphoshikimate = chorismate + phosphate.UniRule annotation

Cofactori

Pathwayi: chorismate biosynthesis

This protein is involved in step 7 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 (aroG1)
  2. 3-dehydroquinate synthase (aroB)
  3. 3-dehydroquinate dehydratase (aroQ)
  4. Shikimate dehydrogenase (NADP(+)) (aroE)
  5. Shikimate kinase (aroK), Shikimate kinase (aroK)
  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.

100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
