Mode of substrate carboxyl binding to the [4Fe-4S]+ cluster of reduced aconitase as studied by 17O and 13C electron-nuclear double resonance spectroscopy.

The active form of aconitase has a diamagnetic [4Fe-4S]2+ cluster. A specific iron ion (Fea, which is lost during inactivation) is the binding site for substrate, as shown by Mössbauer spectroscopy. We have studied the mode of substrate and analogue binding at equilibrium to the paramagnetic [4Fe-4S...
