structure of the mutant R73V/R84A with 1alpha,25-dihydroxyvitamin D3, a hydrogen-bond network including the 1alpha-hydroxyl group and several water molecules play an important role in the substrate-binding for 26-hydroxylation
wild-type to 1.5 A resolution, and mutant R84A, native protein and in complex with 1alpha,25-dihydroxyvitamin D3. The compound is positioned 11 A from the iron atom along the I helix within the pocket. The loss of two hydrogen bonds in the R84A mutant increases the adaptability of the B and F helices, creating a transient binding site
