Chorismate mutase (CM) EC:5.4.99.5 catalyses the the conversion of chorismate to prephenate in the shikimate pathway of tyrosine and phenylalanine biosynthesis in bacteria, fungi and plants [1,2]. 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.	Domain
