| Section2 = }} 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 * 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", because the compound plays a role as a branch-point in aromatic amino acid biosynthesis. == Biosynthesis == Shikimate → shikimate-3-phosphate → 5-enolpyruvylshikimate-3-phosphate (5-O-(1-carboxyvinyl)-3-phosphoshikimate) : Chorismate synthase is an enzyme that catalyzes the final chemical reaction 5-O-(1-carboxyvinyl)-3-phosphoshikimate → chorismate + phosphate. : 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「chorismic acid」の詳細全文を読む スポンサード リンク
