Chorismate = prephenate
Three active sites are formed in the interstices between three subunits. Each active site is composed of the residues of two adjacent subunits. The two Arg hold the chorismate. Crucial distance between Arg6 and Arg63* controls the conformation of the chorismate. The residues in the close vicinity to the chorismate substrate are Arg6, Glu77, Arg89, Tyr 107, Leu114, and Arg115 from one subunit and Phe57*, Ala59*, Arg63*, Leu72*, and Leu73* from the other subunit. The family of the chorismate mutase enzymes shares a common E.S active site

The average structures of the thermophilic E.S complex at three different temperatures are obtained from the MD simulations. A snapshot of the most important features of the active site of the TtCM E.S complex at 70°C is shown. At this temperature the Boltzmann distribution is primarily composed of reactive conformers - near attack conformers (NACs). The effects of the different temperatures on the distances in the structure are shown. The distances between electrostatic and hydrophobic pairs decrease as temperature decreases
