== Function ==
[https://www.uniprot.org/uniprot/ATPF_ACIBT ATPF_ACIBT] F(1)F(0) ATP synthase produces ATP from ADP in the presence of a proton or sodium gradient. F-type ATPases consist of two structural domains, F(1) containing the extramembraneous catalytic core and F(0) containing the membrane proton channel, linked together by a central stalk and a peripheral stalk. During catalysis, ATP synthesis in the catalytic domain of F(1) is coupled via a rotary mechanism of the central stalk subunits to proton translocation.[HAMAP-Rule:MF_01398] Component of the F(0) channel, it forms part of the peripheral stalk, linking F(1) to F(0).[HAMAP-Rule:MF_01398]

== Publication Abstract from PubMed ==
The global spread of multidrug-resistant Acinetobacter baumannii infections urgently calls for the identification of novel drug targets. We solved the electron cryo-microscopy structure of the F(1)F(o)-adenosine 5'-triphosphate (ATP) synthase from A. baumannii in three distinct conformational states. The nucleotide-converting F(1) subcomplex reveals a specific self-inhibition mechanism, which supports a unidirectional ratchet mechanism to avoid wasteful ATP consumption. In the membrane-embedded F(o) complex, the structure shows unique structural adaptations along both the entry and exit pathways of the proton-conducting a-subunit. These features, absent in mitochondrial ATP synthases, represent attractive targets for the development of next-generation therapeutics that can act directly at the culmination of bioenergetics in this clinically relevant pathogen.
