This family includes the catalytic regions of the chorismate binding enzymes anthranilate synthase, isochorismate synthase, aminodeoxychorismate synthase and para-aminobenzoate synthase.

1: The structures of anthranilate synthase of Serratia marcescens crystallized in the presence of (i) its substrates, chorismate and glutamine, and a product, glutamate, and (ii) its end-product inhibitor, L-tryptophan.
