WebJun 15, 2008 · The presence of an enzyme-bound persulfide at the end of the reaction was unambiguously demonstrated in the case of NifS from A. vinelandii [69] and later from the … 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…
