Association of a phosphate ion with the phosphate-binding or P-loops of the α-subunit from P. denitrificans and of the βE-subunit from bovine F1-ATPase inhibited with the ATP analogue AMP-PNP (adenylylimidodiphosphate; PDB entry 1h8h
; Menz et al., 2001). (a) The P-loops of the α-subunit from P. denitrificans (residues 169–176) shown in deep red and (b) the P-loops of the the bovine β-subunit (residues 157–163) shown in yellow. The bound phosphate ions are shown in orange and red. In (c), for reference, ATP is shown bound to the nucleotide-binding site of the αE-subunit of bovine F1-ATPase (PDB entry 1h8h
). |
