ProteomicsOverlapping binding site for ferredoxin and frataxin on yeast cysteine desulfurase participating in FeS cluster biogenesis
In mitochondria cysteine desulfurase (Nfs1) plays a central role in the biosynthesis of iron-sulfur (FeS) clusters, cofactors critical for activity of many cellular proteins. Nfs1 functions both as a sulfur donor for cluster assembly and as a binding platform for other proteins functioning in the pr...

ProteomicsAnalysis of reconstituted tripartite complex supports avidity-based recruitment of Hsp70 by substrate bound J-domain protein
Hsp70 are ubiquitous, versatile molecular chaperones that cyclically interact with substrate protein(s). The initial step requires synergistic interaction of a substrate and a J-domain protein (JDP) cochaperone, via its J-domain, with Hsp70 to stimulate hydrolysis of its bound ATP. This hydrolysis d...
