3.A.2.1.7
F-type ATPase.  The enzyme can synthesize but not hydrolyze ATP due to the presence of the zeta inhibitor.  The crystal structure is known (Morales-Rios et al. 2015).  The complex that was crystallized contains the nine core proteins of the complete F-ATPase complex plus the zeta inhibitor protein. The formation of crystals depended upon the presence of bound bacterial cardiolipin and phospholipid molecules; when they were removed, the complex failed to crystallize.
