(A) Dibutyl PI(4)P and waters from the final refined model overlaid with electron density from the σA-weighted 2|Fo| - |Fc| map calculated before addition of the ligand/solvent and contoured at 1.0 σ.
(B) Polar contacts between DrrA and the lower (left) and upper (right) regions of dibutyl PI(4)P.
(C) View of the P4M domain and dibutyl PI(4)P colored according to buried surface area upon complex formation.
