  • Iron-Sulfur Cluster an overview ScienceDirect Topics

    Moreover, due to their chemical nature, iron–sulfur clusters serve as iron and sulfur repositories, donating these ions when needed. Thus, they play significant roles in iron and sulfide sensing [26,47,48]. Many iron–sulfur enzymes contain the cluster near or at the active site, indicating key roles of these cofactors in catalysis [49–51].

  • Putative Iron-Sulfur Proteins Are Required for Hydrogen

    In this work, we used genetic approaches to confirm that two putative iron-sulfur cluster proteins encoded on the hydrogenase structural operons, HucE and HhyE, are required for H 2 consumption in M. smegmatis. Sequence analysis show that these proteins, while homologous, fall into distinct phylogenetic clades and have distinct metal-binding

    SUMMARY Iron-sulfur (Fe-S) clusters are required for critical biochemical pathways, including respiration, photosynthesis, and nitrogen fixation. Assembly of these iron cofactors is a carefully controlled process in cells to avoid toxicity from free iron and sulfide. Multiple Fe-S cluster assembly pathways are present in bacteria to carry out basal cluster assembly, stress-responsive cluster

    a. Iron–Sulfur Clusters. These are redox active. They commonly occur as prosthetic groups in iron–sulfur proteins. There are four common types of iron–sulfur clusters: Those designated [2Fe–2S] and [4Fe–4S]. Clusters consist of equal numbers of iron and sulfide ions and are both coordinated to four protein Cys sulfhydryl groups.
