Chorismic acid, more commonly known as its anionic form chorismate, is an important biochemical intermediate in plants and microorganisms. It is a precursor for:
- The aromatic amino acids phenylalanine and tyrosine
- Indole, indole derivatives and tryptophan
- 2,3-dihydroxybenzoic acid (DHB) used for enterobactin biosynthesis
- The plant hormone salicylic acid[1]
- Many alkaloids and other aromatic metabolites.
[edit] Biosynthesis
Shikimate → shikimate-3-phosphate → 5-enolpyruvylshikimate-3-phosphate → chorismate.
