Figure 1 Stereo figure of the active site of monomer B in the hPDE10a-papaverine crystal structure. F[o] - F[c] electron density is contoured at 2.0 . Hydrogen-bonding interactions are shown as dotted lines to Gln726. The protein and papaverine are shown as a stick models with green and magenta C atoms, respectively. Zinc and magnesium are shown as purple and red spheres, respectively.
