Structure and Mechanism of the Human FE-S Cluster Assembly Complex
Metal ions are essential to life as they augment amino acid protein chemistry and thereby catalyze many difficult biological reactions. As “free” metal ions are toxic and indiscriminately reactive, critical protein systems have evolved to sequester, chaperone, and regulate metal ion concentrations. Defects in these systems lead to metal ion metabolic disease and result in cellular, tissue, and systemic pathology. The iron-sulfur cluster assembly pathway contains a conserved set of metallochaperone proteins that recognize and insert Fe-S clusters into apo metalloproteins. We determined the first crystal structure for the NFS1-ISD11-ACP cysteine desulfurase, which is a central enzyme in this…
