Figure 2
Stereoview of the OMIT map of oxalate and interactions in the active site. The OMIT FoFc difference density map is shown as green chicken wire and contoured at 3σ. The protein main chain is shown in ribbon format coloured according to subunit: yellow, subunit A; orange, subunit B; purple, subunit D. Side chains are shown as sticks coloured red for O atoms, blue for N atoms, orange for P atoms and according to subunit as before for C atoms. The oxalate and AMP C positions are shown in black. Water molecules are depicted as cyan spheres. Dashed lines represent potential hydrogen-bonding interactions.
