Structural and biochemical investigations of a HEAT-repeat protein involved in the cytosolic iron-sulfur cluster assembly pathway [PDF]

open access: yesCommunications Biology, 2023
Iron-sulfur clusters are essential for life and defects in their biosynthesis lead to human diseases. The mechanism of cluster assembly and delivery to cytosolic and nuclear client proteins via the cytosolic iron-sulfur cluster assembly (CIA) pathway is ...

Crystallographic characterization of the high-potential iron-sulfur protein in the oxidized state at 0.8 Å resolution. [PDF]

open access: yesPLoS ONE, 2017
High-potential iron-sulfur protein (HiPIP) is a soluble electron carrier protein of photosynthetic bacteria with an Fe4S4 cluster. Although structural changes accompanying the electron transfer are important for understanding of the functional mechanism,

Sulfur Administration in Fe–S Cluster Homeostasis

open access: yesAntioxidants, 2021
Mitochondria are the key organelles of Fe–S cluster synthesis. They contain the enzyme cysteine desulfurase, a scaffold protein, iron and electron donors, and specific chaperons all required for the formation of Fe–S clusters.

Biophysical Characterization of Iron-Sulfur Proteins

open access: yesBio-Protocol, 2021
Iron-sulfur proteins are primordial catalysts and biological electron carriers that today drive major metabolic pathways across all forms of life. They can access a diversity of oxidation states and can mediate electron transfer over an extended range of

Iron–Sulfur Cluster Biogenesis and Iron Homeostasis in Cyanobacteria

open access: yesFrontiers in Microbiology, 2020
Iron–sulfur (Fe–S) clusters are ancient and ubiquitous cofactors and are involved in many important biological processes. Unlike the non-photosynthetic bacteria, cyanobacteria have developed the sulfur utilization factor (SUF) mechanism as their main ...

UV-light-driven prebiotic synthesis of iron–sulfur clusters [PDF]

open access: yes, 2017
Iron–sulfur clusters are ancient cofactors that play a fundamental role in metabolism and may have impacted the prebiotic chemistry that led to life.

Interaction of the Streptomyces Wbl protein WhiD with the principal sigma factor σHrdB depends on the WhiD [4Fe-4S] cluster [PDF]

open access: yes, 2020
The bacterial protein WhiD belongs to the Wbl family of iron–sulfur [Fe-S] proteins present only in the actinomycetes. In Streptomyces coelicolor, it is required for the late stages of sporulation, but precisely how it functions is unknown.

Iron–sulfur clusters: from metals through mitochondria biogenesis to disease [PDF]

open access: yes, 2018
Iron–sulfur clusters are ubiquitous inorganic co-factors that contribute to a wide range of cell pathways including the maintenance of DNA integrity, regulation of gene expression and protein translation, energy production, and antiviral response ...

Description of peptide bond planarity from high-resolution neutron crystallography

open access: yesBiophysics and Physicobiology, 2023
Neutron crystallography is a highly effective method for visualizing hydrogen atoms in proteins. In our recent study, we successfully determined the high-resolution (1.2 Å) neutron structure of high-potential iron-sulfur protein, refining the coordinates
