Iron–sulfur cluster sensor-regulators
Current Opinion in Chemical Biology, 2012Regulatory proteins that contain an iron-sulfur cluster cofactor constitute a group that is growing both in number and importance, with a range of functions that include sensing of molecular oxygen, stress response, and iron regulation. In all cases, the cluster plays a central role, as a sensory module, in controlling the activity of the regulator. In

Iron-sulfur clusters are universally distributed groups occurring in iron-sulfur proteins. They have a wide range of cellular functions which reflect the chemistry of the clusters. Some clusters are involved in electron transport and energy transduction in photosynthesis and respiration.

Iron–sulfur clusters: Why iron?
Journal of Inorganic Biochemistry, 2006This communication addresses a simple question by means of density functional calculations: Why is iron used as the metal in iron-sulfur clusters? While there may be several answers to this question, it is shown here that one feature - the well-defined inner-sphere reorganization energy of self-exchange electron transfer - is very much favored in iron ...

Iron-sulphur cluster assembly enzyme, ISCU, is a protein coding gene which is engaged in repression of mitochondrial metabolism. In human, the two isoforms of ISCU exist as iron-sulphur (Fe-S) cluster scaffold protein, ISCU1 and ISCU2. ISCU1 is located in cytosol while ISCU2 presents in mitochondria. ISCU1 and ISCU2 promote the assembly of iron-sulphur

Iron–Sulfur Cluster-based Sensors
2017Iron–sulfur cluster proteins fulfil a wide range of functions in biology, the most recently discovered of which is as regulatory proteins that control the cellular response to a variety of environmental stimuli that cause intracellular changes. The inherent reactivity of iron–sulfur clusters, particularly towards small (gas) molecules, makes them ideal

All-Ferrous Iron–Sulfur Clusters
2012Iron–sulfur clusters are important biological cofactors that are used for electron transfer and also for reactivity. Though the iron atoms in these clusters are typically a mixture of ferrous iron(II) and ferric iron(III), there have been reports of biological iron–sulfur clusters in which all the iron atoms are reduced to the iron(II) oxidation state.
