The Hsp70 chaperone Ssq1p is dispensable for iron-sulfur cluster formation on the scaffold protein Isu1p.
The specialized yeast mitochondrial chaperone system, composed of the Hsp70 Ssq1p, its co-chaperone J-protein Jac1p, and the nucleotide release factor Mge1p, perform a critical function in the biogenesis of iron-sulfur (Fe/S) proteins. Using a spectroscopic assay, we have analyzed the potential role of the chaperones in Fe/S cluster assembly on the scaffold protein Isu1p in vitro in the presenc...

The Role of CyaY in Iron Sulfur Cluster Assembly on the E. coli IscU Scaffold Protein
Progress in understanding the mechanism underlying the enzymatic formation of iron-sulfur clusters is difficult since it involves a complex reaction and a multi-component system. By exploiting different spectroscopies, we characterize the effect on the enzymatic kinetics of cluster formation of CyaY, the bacterial ortholog of frataxin, on cluster formation on the scaffold protein IscU. Frataxin...
متن کاملAssembly and Transfer of Iron–Sulfur Clusters in the Plastid
Iron-Sulfur (Fe-S) clusters and proteins are essential to many growth and developmental processes. In plants, they exist in the plastids, mitochondria, cytosol, and nucleus. Six types of Fe-S clusters are found in the plastid: classic 2Fe-2S, NEET-type 2Fe-2S, Rieske-type 2Fe-2S, 3Fe-4S, 4Fe-4S, and siroheme 4Fe-4S. Classic, NEET-type, and Rieske-type 2Fe-2S clusters have the same 2Fe-2S core; ...
متن کاملAn Ipomoea batatas Iron-Sulfur Cluster Scaffold Protein Gene, IbNFU1, Is Involved in Salt Tolerance
Iron-sulfur cluster biosynthesis involving the nitrogen fixation (Nif) proteins has been proposed as a general mechanism acting in various organisms. NifU-like protein may play an important role in protecting plants against abiotic and biotic stresses. An iron-sulfur cluster scaffold protein gene, IbNFU1, was isolated from a salt-tolerant sweetpotato (Ipomoea batatas (L.) Lam.) line LM79 in our...
