The [4Feâ4S] cluster is ubiquitous to a class of base excision repair enzymes in organisms ranging from bacteria to man and was first considered as a structural element, owing to its redox stability under physiological conditions.
The valence electrons are those in the 4s and the 3d levels. 1s2 2s2 2p6 3s2 3p6 4s2 3d6 so there are 8 valence electrons. thought the 4s are lost first giving Fe2+ (1s2 2s2 2p6 3s2 3p6 3d6) and Fe3+ (1s2 2s2 2p6 3s2 3p6 3d5)
