Structural model for the tryptophan synthase α2β2 bienzyme complex showing important features of the subunits, sites, coenzyme PLP and the interconnecting tunnel. The IGP analogue, indole 3-propanol phosphate (IPP) is bound to the active sites of the α-subunits. Figure modified from Hyde et al. [21].
