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

FMNH2UniRule annotationNote: Reduced FMN (FMNH(2)).UniRule annotation

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 (aroG)
  2. 3-dehydroquinate synthase (aroB)
  3. 3-dehydroquinate dehydratase (aroQ)
  4. no protein annotated in this organism
  5. Shikimate kinase (aroK)
  6. 3-phosphoshikimate 1-carboxyvinyltransferase (aroA_1)
  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.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
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.
