BOVINE MITOCHONDRIAL F1-ATPASE COMPLEXED WITH THE INHIBITOR PROTEIN IF1
OverviewOverview
In mitochondria, the hydrolytic activity of ATP synthase is prevented by, an inhibitor protein, IF1. The active bovine protein (84 amino acids) is, an alpha-helical dimer with monomers associated via an antiparallel, alpha-helical coiled coil composed of residues 49-81. The N-terminal, inhibitory sequences in the active dimer bind to two F1-ATPases in the, presence of ATP. In the crystal structure of the F1-IF1 complex at 2.8 A, resolution, residues 1-37 of IF1 bind in the alpha(DP)-beta(DP) interface, of F1-ATPase, and also contact the central gamma subunit. The inhibitor, opens the catalytic interface between the alpha(DP) and beta(DP) subunits, relative to previous structures. The presence of ATP in the catalytic site, of the beta(DP) subunit implies that the inhibited state represents ... [(full description)]
