[2Fe-2S] cluster assembly
Definition
Target type: biologicalprocess
The incorporation of two iron atoms and two sulfur atoms into an iron-sulfur cluster. [GOC:jl, GOC:mengo_curators, GOC:pde, GOC:tt, GOC:vw, PMID:15952888]
[2Fe-2S] cluster assembly is a complex process that involves multiple proteins and steps. It begins with the synthesis of the iron-sulfur (Fe-S) cluster precursor, which is a simple inorganic complex of iron and sulfide ions. This precursor is then assembled into the final [2Fe-2S] cluster, which is a more complex structure that contains two iron atoms and two sulfur atoms. The assembly process takes place in a protein scaffold known as the scaffold protein.
The scaffold protein binds to the Fe-S cluster precursor and then uses a series of enzymatic reactions to assemble the final [2Fe-2S] cluster. These reactions involve the transfer of electrons and protons, as well as the formation of new chemical bonds. Once the [2Fe-2S] cluster is assembled, it is transferred to its target protein.
The target protein is typically an enzyme that requires a [2Fe-2S] cluster for its function. The cluster is incorporated into the protein's active site, where it plays a role in the enzyme's catalytic activity.
In summary, the biological process of [2Fe-2S] cluster assembly can be broken down into the following steps:
1. **Synthesis of the Fe-S cluster precursor** This involves the combination of iron and sulfide ions.
2. **Assembly of the [2Fe-2S] cluster** This occurs within a protein scaffold known as the scaffold protein.
3. **Transfer of the [2Fe-2S] cluster to its target protein** This involves the incorporation of the cluster into the target protein's active site.
[2Fe-2S] cluster assembly is a vital process for many cellular functions. These clusters are required for a variety of enzymatic reactions, including electron transport, DNA replication, and the metabolism of iron and sulfur. Defects in [2Fe-2S] cluster assembly can lead to a number of human diseases, including Friedreich's ataxia and mitochondrial disorders.'
