Allosteric chorismate mutase [48604] (1) duplication: 2 weak structural repeats resembling subunits of E. coli protein
monomeric chorismate mutase [140942] (1) "un-swapped" four-helical relative of the homodimeric chorismate mutase domain
Secreted chorismate mutase-like [140945] (1) duplication; two structural repeats, like in the yeast enzyme, but with a different location of the remaining active site
