X-ray crystallography has defined atomic structures of several related P-type ATPases. We have determined a structure of CopA at 10 Å resolution by cryo-electron microscopy of a new crystal form and used computational molecular docking to study the interactions between the N-terminal metal-binding domain (NMBD) and other elements of the molecule. We found that the shorter-chain lipids used to produce these crystals are associated with movements of the cytoplasmic domains, with a novel dimer interface and with disordering of the NMBD, thus offering evidence for the transience of its interaction with the other cytoplasmic domains. Docking identified a binding site that matched the location of the NMBD in our previous structure by cryo-electron microscopy, allowing a more detailed view of its binding configuration and further support for its role in autoinhibition.

Dialysis was carried out for 5 days in 50 ul dialysis buttons at 30 degrees C against 500 mL of 50 mM MES, pH 6.1, 25 mM Na2SO4, 25 mM K2SO4, 200 uM BCDS, 10 mM MgSO4, and 2 mM beta-mercaptoethanol. Stock solutions of lipid were made in dodecyl octaethylene glycol ether (C12E8) at 1 mg lipid per 2 mg detergent. Number unique components: 1
