The three types of CM are AroH class, AroQ class, prokaryotic type and AroQ class, eukaryotic type. Structurally CMs can be divided into two main groups: type I (AroH) class and type II (AroQ). Type I (AroH) CMs include CMs characterised by a trimeric pseudo alpha/beta barrel structure [2]. The two types of the AroQ structural class (the Escherichia coli CM dimer and the yeast CM monomer) can be structurally superimposed, and the topology of the four-helix bundle forming the active site is conserved [3]. CMs can be monofunctional or bifunctional (generally fused to another shikimate pathway member). Despite the structural differences, all CMs perform the same basic reaction [2]. This entry represents chorismate mutases of the AroH class predominantly from Terrabacteria.

chorismate mutase (AroH)  M-CSA #474

Chorismate mutase (CM; EC:5.4.99.5) catalyses the rearrangement of chorismate to prephenat, 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.

This entry represents a family of monofunctional (non-fused) chorismate mutases from Gram-positive bacteria (Firmicutes) and cyanobacteria. They are monofunctional, homotrimeric, non-allosteric enzymes and are not regulated by the end-product aromatic amino acids (unlike those CMs of the AroQ-type).
