Chorismate
Chorismic acid
Chemical compound
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, tryptophan, 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.
- The folate precursor para-aminobenzoate (pABA)
- The biosynthesis of vitamin K and folate in plants and microorganisms.
The name chorismic acid derives from a classical Greek word χωρίζω meaning "to separate",[2] because the compound plays a role as a branch-point in aromatic amino acid biosynthesis.[3]
