Remarkably, the dissociation resulted in the formation of a neutral but excited sulfur atom, even though multiple electrons ...

New iron and sulfur atom assemblies. Other than the common [2Fe-2S], [3Fe-4S] and [4Fe-4S] clusters of Figure 1, the following structures have been discovered: (i) clusters with larger ...

Surprisingly, the biosynthesis of this simple derivative requires a minimum of four sulfur transfer reactions involving seven proteins. To identify genes required for tRNA modification ...

Iron is an element. It is made of only one type of atom: iron atoms. Sulfur is another element. It contains only sulfur atoms, and nothing else, so it is pure. When we mix two different pure ...
