Schematic diagrams showing the predicted interactions of the coenzymes with wild-type PsXR. A) with NAD⁺; B) with NADP⁺. The predition is based on the coenzyme binding sites in CtXR [8]. And the residues predicted to be involved in coenzyme binding in PsXR are exactly the same as the corresponding CtXR residues (indicated in brackets). The corresponding CtXR residues are indicated in brackets.
