Classification of nucleotide binding sites on mitochondrial F1-ATPase from yeast.
Methods are described to classify nucleotide binding sites of the mitochondrial coupling factor F1 from yeast on the basis of their affinities and stability properties. High affinity sites or states for ATP and related adenine analogs and low affinity sites or states which bind a broad range of different nucleotide triphosphates are found. The results are discussed in terms of a two site, two cycle scheme, where binding of nucleotide at one site facilitates the release of nucleotide at a second site.
