In enzymology, chorismate mutase (EC 5.4.99.5) is an enzyme that catalyzes the chemical reaction for the conversion of chorismate to prephenate in the pathway to the production of phenylalanine and tyrosine, also known as the shikimate pathway.Hence, this enzyme has one substrate, chorismate, and one product, prephenate. Chorismate mutase is found at a branch point in the pathway. The enzyme channels the substrate, chorismate to the biosynthesis of tyrosine and phenylalanine and away from tryptophan.

  • In enzymology, chorismate mutase (EC 5.4.99.5) is an enzyme that catalyzes the chemical reaction for the conversion of chorismate to prephenate in the pathway to the production of phenylalanine and tyrosine, also known as the shikimate pathway.Hence, this enzyme has one substrate, chorismate, and one product, prephenate. Chorismate mutase is found at a branch point in the pathway. The enzyme channels the substrate, chorismate to the biosynthesis of tyrosine and phenylalanine and away from tryptophan. Its role in maintaining the balance of these aromatic amino acids in the cell is vital. This is the single known example of a naturally occurring enzyme catalyzing a pericyclic reaction. Chorismate mutase is only found in fungi, bacteria, and higher plants. Some varieties of this protein may use the morpheein model of allosteric regulation. (en)
  • La chorismate mutase est une isomérase qui catalyse la réaction : chorismate préphénate. Cette enzyme intervient notamment, à la suite de la voie du shikimate, dans la biosynthèse d'acides aminés aromatiques tels que la phénylalanine et la tyrosine. On la trouve chez les bactéries, les mycètes et les plantes vasculaires. Il s'agit de la seule enzyme connue du milieu naturel catalysant une réaction péricyclique. Elle joue un rôle déterminant dans le maintien de l'équilibre physiologique dans la cellule entre d'une part les acides aminés aromatiques dont elle permet la synthèse, et d'autre part les autres acides aminés. Elle fait partie des protéines dont la régulation allostérique serait de type morphéine. (fr)
