Abstract

Abstract: The physiological transient complex between cytochrome f (Cf) and cytochrome c 6 (Cc 6) from the cyanobacterium Nostoc sp. PCC 7119 has been analysed by NMR spectroscopy. The binding constant at low ionic strength is 8±2mM−1, and the binding site of Cc 6 for Cf is localized around its exposed haem edge. On the basis of the experimental data, the resulting docking simulations suggest that Cc 6 binds to Cf in a fashion that is analogous to that of plastocyanin but differs between prokaryotes and eukaryotes.
