WebAssembly of iron-sulfur (Fe-S) clusters and maturation of Fe-S proteins in vivo require complex machineries. In Escherichia coli, under adverse stress conditions, this process is achieved by the SUF system that contains six proteins as … The assembly of iron-sulfur clusters cluster begins with the production of the equivalent of a sulfur (sulfur atoms per se are not found in nature). The required S atom is obtained from cysteine by the action of so-called cysteine desulfurases. One prominent desulfurase is called Isc. Not only is cysteine the source of S, a cysteine residue in IscS is participates in the abstration. Furthermore, a cysteine residue is the partner protein IscU plays a role is relaying the S atom to ir…
WebNov 29, 2024 · Iron-sulfur (Fe-S) clusters are iron-containing prosthetic groups and enzymatic cofactors.
