http://purl.uniprot.org/citations/22813754 | http://www.w3.org/2000/01/rdf-schema#comment | "Cysteine desulfurases generate a covalent persulfide intermediate from cysteine, and this activated form of sulfur is essential for the synthesis of iron-sulfur (Fe-S) clusters. In yeast mitochondria, there is a complete machinery for Fe-S cluster synthesis, including a cysteine desulfurase, Nfs1p. Here we show that following supplementation of isolated mitochondria with [(35)S]cysteine, a radiolabeled persulfide could be detected on Nfs1p. The persulfide persisted under conditions that did not permit Fe-S cluster formation, such as nucleotide and/or iron depletion of mitochondria. By contrast, under permissive conditions, the radiolabeled Nfs1p persulfide was greatly reduced and radiolabeled aconitase was formed, indicating transfer of persulfide to downstream Fe-S cluster recipients. Nfs1p in mitochondria was found to be relatively more resistant to inactivation by N-ethylmaleimide (NEM) as compared with a prokaryotic cysteine desulfurase. Mitochondria treated with NEM (1 mM) formed the persulfide on Nfs1p but failed to generate Fe-S clusters on aconitase, likely due to inactivation of downstream recipient(s) of the Nfs1p persulfide. Thus the Nfs1p-bound persulfide as described here represents a precursor en route to Fe-S cluster synthesis in mitochondria."xsd:string |
