Figure 3 Ribbon representation of MjNK. (a) Crystallographic dimer of the apo form (subunit A, purple; subunit A', pink) and (b) in complex with adenosine (red) and AMP-PNP (yellow). Subunit A (dark blue) is in the closed conformation with the lid domain closer to the / -domain and contains the strongly bound adenosine, whereas subunit B (light blue) is in the open conformation and contains an adenosine that is bound with low occupancy. Mg atoms and surrounding waters are shown as green and red spheres, respectively.
