Iron sulfur cluster biogenesis
WebNov 5, 2024 · Proteins containing iron-sulfur (Fe-S) clusters are present in almost all living organisms. They have diverse and often essential functions, for example, electron carriers in redox reactions, in redox sensing, oxidative stress defense, biosynthesis of metal-containing cofactors, DNA replication and repair, regulation of gene expression, and tRNA modification. WebIron–sulfur (Fe–S) clusters are critical cofactors that aid in a wide variety of cellular functions (e.g., DNA metabolism and electron transport). In this article, we theorize that a …

WebPumping iron and sulfur: Several iron–sulfur cluster ( [Fe S]) biogenesis systems exist. In bacteria the ISC ( i ron– s ulfur c luster) and SUF (mobilisation of su l f ur) pathways are coordinated through the transcription factor IscR.
WebMar 16, 2010 · Since the SUF system is the essential iron-sulfur cluster biogenesis system in B. subtilis, its upregulation under copper stress gave evident support for impaired assembly already during the initial steps of cluster biogenesis. To assess whether SufU was affected on the protein level under copper stress, WT cells were grown with different ... WebHere, we constructed and expressed dominant–negative variants of the primary Fe-S biogenesis scaffold protein iron–sulfur cluster assembly enzyme 2 (ISCU2) in human HEK293 cells. This approach enabled us to study the early metabolic reprogramming associated with loss of Fe-S–containing proteins in several major cellular compartments.
