The biosynthesis of the Fe–S clusters has been well studied. The biogenesis of iron sulfur clusters has been studied most extensively in the bacteria E. coli and A. vinelandii and yeast S. cerevisiae. At least three different biosynthetic systems have been identified so far, namely nif, suf, and isc systems, which were first identified in bacteria. The nif system is responsible for the clusters in the enzyme nitrogenase. The suf and isc systems are more general. WebINTRODUCTION. As a rule, the loss of iron–sulfur (FeS) clusters is very damaging to the function of FeS proteins. Nitric oxide (NO) radicals provide a prominent pathway for …
