Electron density of SERCA ligands. A peak of ∼6σ in the mFo − DFc OMIT map after refinement without ligands (all atom coordinates, individual B factors) against data to 2.8 Å resolution overlaps with (a) a phosphatidylcholine modelled in the E1–ADP–AlF4 form (stick representation; PDB entry 2zbd ; Toyoshima et al., 2004BB44) and (b) the N-terminal part of regulatory sarcolipin (grey cartoon; PDB entry 4h1w ; Winther et al., 2013BB51). (c) mFo − DFc OMIT map (green, 3.0σ; red, −3.0σ) calculated to 5 Å resolution at the vanadate- and TNPATP-binding sites. The side chain of the catalytic residue Asp351 is shown in stick representation.
