2.8.4.3 | [4Fe-4S]-center |
presence of two distinct [4Fe-4S]2+,1+ clusters in the protein. One is coordinated by residues Cys150, Cys154, and Cys157 in the radical-AdoMet motif, and the other is proposed to be coordinated by the three N-terminal conserved cysteines Cys10, Cys46, and Cys79. The two [4Fe-4S]2+ clusters have similar UV-visible absorption, resonance Raman, and Moessbauer properties but differ in terms of redox properties and the EPR properties of the reduced [4Fe-4S]1+ clusters |
