Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance. Ligands: ADP, ATP, MG Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function ATPA_FUSNN Produces ATP from ADP in the presence of a proton gradient across the membrane. The alpha chain is a regulatory subunit. Publication Abstract from PubMed The crystal structure of the F1-catalytic domain of the adenosine triphosphate (ATP) synthase has been determined from the pathogenic anaerobic bacterium Fusobacterium nucleatum. The enzyme can hydrolyse ATP but is partially inhibited. The structure is similar to those of the F1-ATPases from Caldalkalibacillus thermarum, which is more strongly inhibited in ATP hydrolysis, and in Mycobacterium smegmatis, which has a very low ATP hydrolytic activity. The betaE-subunits in all three enzymes are in the conventional 'open' state, and in the case of C. thermarum and M. smegmatis, they are occupied by an ADP and phosphate (or sulfate), but in F. nucleatum, the occupancy by ADP appears to be partial. It is likely that the hydrolytic activity of the F. nucleatum enzyme is regulated by the concentration of ADP, as in mitochondria.
