Iron | in a partially purified fraction the presence of a S2- source and Fe2+ converts the predominant [2Fe-2S] into a 1:1 mixture of [2Fe-2S] and [4Fe-4S], reduced [4Fe-4S] is involved in mediating the cleavage of S-adenosylmethionine and reduced [2Fe-2S] is the sulfur source of biotin | Escherichia coli | |
