While synthesizing ATP, it regulates ATP cleavage by its inhibitory ε subunit to prevent wasteful ATP consumption. We determined cryo-electron microscopy structures of the ATPase active A. baumannii F-αßγε mutant in four distinct conformational states, revealing four transition states and structural transformation of the ε's C-terminal domain, forming the switch of an ATP hydrolysis off- and an ATP synthesis on-state based. These alterations go in concert with altered motions and interactions in the catalytic- and rotary subunits of this engine. These A. baumannii interacting sites provide novel pathogen-specific targets for inhibitors, with the aim of ATP depletion and/or ATP synthesis and growth inhibition. Furthermore, the presented diversity to other bacterial F-ATP synthases extends the view of structural elements regulating such a catalyst.
