Method: Electron Microscopy, Resolution 4.6Å Ligands: ADP, ATP, MG Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function ATPA_ACIBT Produces ATP from ADP in the presence of a proton gradient across the membrane. The alpha chain is a regulatory subunit.[HAMAP-Rule:MF_01346] 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.
