3-phosphoshikimate 1-carboxyvinyltransferase

Gene

aroA

Organism
Streptococcus pneumoniae serotype 4 (strain ATCC BAA-334 / TIGR4)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Catalyzes the transfer of the enolpyruvyl moiety of phosphoenolpyruvate (PEP) to the 5-hydroxyl of shikimate-3-phosphate (S3P) to produce enolpyruvyl shikimate-3-phosphate and inorganic phosphate.UniRule annotation2 Publications

Catalytic activityi

Phosphoenolpyruvate + 3-phosphoshikimate = phosphate + 5-O-(1-carboxyvinyl)-3-phosphoshikimate.UniRule annotation1 Publication

Enzyme regulationi

Competitively inhibited by glyphosate. Avtivated by ammonium, rubidium or potassium ions.1 Publication

    Pathwayi: chorismate biosynthesis

    This protein is involved in step 6 of the subpathway that synthesizes chorismate from D-erythrose 4-phosphate and phosphoenolpyruvate.UniRule annotationCurated
    Proteins known to be involved in the 7 steps of the subpathway in this organism are:
    1. Phospho-2-dehydro-3-deoxyheptonate aldolase (SP_1700), Phospho-2-dehydro-3-deoxyheptonate aldolase (SP_1701)
    2. 3-dehydroquinate synthase (aroB)
    3. 3-dehydroquinate dehydratase (aroD)
    4. Shikimate dehydrogenase (NADP(+)) (aroE)
    5. 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.
    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.
