Chorismic acid

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
 * Many alkaloids and other aromatic metabolites.

Biosynthesis
Shikimate &rarr; shikimate-3-phosphate &rarr; 5-enolpyruvylshikimate-3-phosphate &rarr; chorismate.
