Iron-sulfur cluster biosynthesis.
Iron-sulfur (Fe-S) clusters are present in more than 200 different types of enzymes or proteins and constitute one of the most ancient, ubiquitous and structurally diverse classes of biological prosthetic groups. Hence the process of Fe-S cluster biosynthesis is essential to almost all forms of life and is remarkably conserved in prokaryotic and eukaryotic organisms. Three distinct types of Fe-...
متن کاملCluster characterization in iron-sulfur proteins by magnetic circular dichroism.
We report magnetic circular dichroism (MCD) spectra of 4-Fe iron-sulfur clusters in the iron-sulfur proteins Chromatium high-potential iron protein (HIPIP), Bacillus stearothermophilus ferredoxin and Clostridium pasteurianum ferredoxin. The MCD is found to vary significantly with cluster oxidation state but is relatively insensitive to the nature of the protein. The spectra obtained are compar...
متن کاملBiogenesis of iron-sulfur cluster proteins in plastids.
Iron-sulfur (Fe-S) clusters are co-factors of proteins that perform a number of biological roles, including electron transfer, redox and non-redox catalysis, regulation of gene expression, and as sensors within all living organisms, prokaryotes and eukaryotes. These clusters are thought to be among the oldest structures found in biological cells. In chloroplasts, Fe-S clusters play a key role i...
متن کاملIron-sulfur cluster proteins: electron transfer and beyond.
Iron-sulfur clusters-containing proteins participate in many cellular processes, including crucial biological events like DNA synthesis and processing of dioxygen. In most iron-sulfur proteins, the clusters function as electron-transfer groups in mediating one-electron redox processes and as such they are integral components of respiratory and photosynthetic electron transfer chains and numerou...
متن کاملCancer-Related NEET Proteins Transfer 2Fe-2S Clusters to Anamorsin, a Protein Required for Cytosolic Iron-Sulfur Cluster Biogenesis
Iron-sulfur cluster biogenesis is executed by distinct protein assembly systems. Mammals have two systems, the mitochondrial Fe-S cluster assembly system (ISC) and the cytosolic assembly system (CIA), that are connected by an unknown mechanism. The human members of the NEET family of 2Fe-2S proteins, nutrient-deprivation autophagy factor-1 (NAF-1) and mitoNEET (mNT), are located at the interfac...
