[4Fe4S]2+ clusters exhibit ground-state paramagnetism.

Kresimir Rupnik1, Chi Chung Lee, Yilin Hu, Markus W Ribbe, Brian J Hales.   

Abstract

Two proteins involved in nitrogen fixation contain ferredoxin-type [4Fe4S] clusters that exist in paramagnetic ground state upon oxidation, a property never observed since the discovery of ferredoxins 50 years ago. This unique characteristic suggests a specific coupling in these clusters necessary for nitrogen fixation and implies an evolutionary connection between the clusters in the two proteins.
