Question

If the [Fe_4 S_4]^2+ in a metalloprotein formally containing 2 iron(II) atoms and 2 iron(III) atoms, what ate would it be found after this protein is involved in a one electron transfer process to oxidize a substrate? [Fe_4 S_4]^3 formally containing 1 iron(II) atom and 3 iron(III) atoms. [Fe_4 S_4]^3 formally containing 2 iron(II) atoms and 2 iron(III) atoms. [Fe_4 S_4]^3 formally containing 3 iron(II) atoms and 1 iron(III) atom [Fe_4 S_4] formally containing 3 iron(II) atoms and 1 iron(III) atom [Fe_4 S_4] formally containing 1 iron(II) atom and 3 iron(III) atoms

Explanation / Answer

Ans. On oxidation by 1 electron transfer, one of the fe (II) is converted into Fe(III) and hence there will three Fe (III) and one Fe(II) in a cluster of [Fe4S4}3
