''Toxoplasma gondii'' <snapshot name='84/844927/Cv1/3'>NTPase 2 is dimer of dimers</snapshot> (PDB code [[4a5a]]). The 3D structure of the complex between NTPase 2 and the ATP analog AMPPNP shows the NTPase structure composed of two domains.  Domain I contains the N-terminal and C-terminal and domain II the core residues.  The structure contains 7 Cys-Cys bonds one of which located between domain I and II and reaching the diametrically positioned monomer was found by mutational analysis to be responsible for activation.  The ATP analog - AMPPNP - is located in a cleft and forms interactions with domain I and domain II<ref>PMID:22130673</ref>.
