chorismate mutase (AroQ)  M-CSA #81

Chorismate mutase (CM; EC:5.4.99.5) catalyses the reaction at the branch point of the biosynthetic pathway leading to the three aromatic amino acids, phenylalanine, tryptophan and tyrosine (chorismic acid is the last common intermediate, and CM leads to the L-phenylalanine/L-tyrosine branch). It is part of the shikimate pathway, which is present only in bacteria, fungi and plants. Members of this family, which are restricted to plants and fungi, contain a chorismate mutase domain of the AroQ class (eukaryotic type) and have an all-helical structure. The monomer consists of a catalytic and a regulatory domain covalently linked by a loop, which functions as a molecular hinge. They are monofunctional, allosteric enzymes and are subject to allosteric inhibition by tyrosine and activation by tryptophan.
