The high potential iron-sulfur cluster of aconitase is a binuclear iron-sulfur cluster.

Journal of Biological Chemistry, 1979
It has been reported (Ruzicka, F.J., and Beinert, H. (1978) J. Biol. Chem. 253, 2514-2517) that aconitase in the oxidized state, as isolated, shows an electron paramagnetic resonance signal centered at g = 2.01, typical of high potential iron-sulfur proteins.

Degradation Mechanisms in PEM Water Electrolysis: Diagnosis and Impact

Advanced Materials Technologies, EarlyView.
This review provides an analysis of degradation mechanisms in proton electrolyte membrane water electrolyzers (PEMWE), focusing on all key components. It discusses diagnostic and measurement techniques for evaluating degradation, less‐studied mechanisms, and an expert survey.

A Mussel‐Inspired Bioadhesive Patch to Selectively Kill Glioblastoma Cells

Advanced Science, EarlyView.
An innovative mussel‐inspired bioadhesive patch has been developed for post‐surgical glioblastoma treatment. The patch, which adheres strongly in biological environments, releases a localized treatment. This treatment, acting via reactive oxygen species, shows specific toxicity to glioblastoma cells.

Electronic Structure Reorganization in MPS3 via d‐Shell‐Selective Alkali Metal Doping

Advanced Science, EarlyView.
Alkali metal doping of layered MPS3 antiferromagnets reveals d‐shell‐selective responses. While MnPS3 resists charge transfer due to its half‐filled 3d5 shell, FePS3 and NiPS3 behave similarly to CoPS3 by accommodating extra d‐electrons. Yet only CoPS3, with its least stable d‐shell, undergoes pronounced band restructuring and a semiconducting‐to ...

Structure and functional dynamics of the mitochondrial Fe/S cluster synthesis complex

Nature Communications, 2017
Fe/S clusters are synthesized by the mitochondrial iron-sulfur cluster assembly (ISC) machinery. Here the authors combine crystallography and small angle X-ray scattering measurements to structurally characterize the core ISC complex and give functional ...

Bimetallic Peroxide Nanocomposites‐Driven Redox Dyshomeostasis to Activate Sequential Cuproptosis and Pyroptosis for Amplified Tumor Immunotherapy

Advanced Science, EarlyView.
Hyaluronic acid‐modified bimetallic peroxide nanocomposites (MgO2‐CuO2@HA) are designed for synergistic tumor therapy. The nanocomposites release Mg2+, H2O2, and Cu2+ in tumor cells, induce cuproptosis via Cu+‐mediated protein aggregation, and activate pyroptosis through caspase‐1/gasdermin D pathways for inducing immunogenic cell death, collectively ...

Exome sequencing identifies NFS1 deficiency in a novel Fe‐S cluster disease, infantile mitochondrial complex II/III deficiency

Molecular Genetics & Genomic Medicine, 2014
Iron‐sulfur (Fe‐S) clusters are a class of highly conserved and ubiquitous prosthetic groups with unique chemical properties that allow the proteins that contain them, Fe‐S proteins, to assist in various key biochemical pathways.

Cuproptosis and Disulfidptosis Converge to Empower PD‐L1 Checkpoint Therapy via Cadict‐Induced PD‐L1 Translation

Advanced Science, EarlyView.
This study introduces Cadict, an EGFR‐targeted nanodrug that co‐delivers cuproptosis and disulfidptosis inducers to overcome immune resistance. Cadict synergistically enhances tumor cytotoxicity and sensitizes cancers to ICIs by upregulating PD‐L1 via an Eif5b‐dependent translation mechanism, fostering a potent antitumor immune response and ...

Structure of a Wbl protein and implications for NO sensing by M. tuberculosis

Nature Communications, 2017
Mycobacterium tuberculosis WhiB1 is a DNA-binding protein with a NO sensitive [4Fe-4S] cluster. Here the authors present the NMR structure of WhiB1 and suggest how loss of the iron-sulfur cluster through nitrosylation affects WhiB1 DNA binding and leads ...
