Equilibrium dialysis measurements of adenine nucleotide binding to chloroplast coupling factor 1 suggest that the enzyme has six binding sites for ADP, adenylyl-beta,gamma-imidodiphosphate (AMP-PNP), and 2'(3')-O-2,4,6-trinitrophenyl-ATP (TNP-ATP). High affinity binding at all six sites requires the divalent cation, Mg2+. Three of the nucleotide-binding sites, sites 1, 2, and 3, have ... More
