Purification and structural characterization of the Na+-translocating ferredoxin: NAD+ reductase (Rnf) complex of Clostridium tetanomorphum [PDF]
Nature Communications, 2022 Rnf reversibly reduces NAD+ by ferredoxin coupled with Na+/H+ pumping for microbial ion gradient or reduced ferredoxin formation. Here, a cryo-EM structure provides information about the participating iron and flavin cofactors, the electron transfer ...

Ferredoxin binding site on ferredoxin: NADP+ reductase [PDF]
European Journal of Biochemistry, 1993 The chloroplast enzyme ferredoxin:NADP+ reductase (FNR) catalyzes the reduction of NADP+ by ferredoxin (Fd). FNR and Fd form a 1:1 complex that is stabilized by electrostatic interactions between acidic residues of Fd and basic residues of FNR. To localize lysine residues at the Fd binding site of FNR, the FNR:Fd complex (both proteins from spinach ...

Functional Characterization of the Eukaryotic Cysteine Desulfurase Nfs1p from Saccharomyces cerevisiae [PDF]
, 2004 Previous studies have indicated that the essential protein Nfs1 performs a crucial role in cellular iron-sulfur (Fe/S) protein maturation. The protein is located predominantly in mitochondria, yet low amounts are present in cytosol and nucleus.

Heterocyst Thylakoid Bioenergetics
Life, 2019 Heterocysts are specialized cells that differentiate in the filaments of heterocystous cyanobacteria. Their role is to maintain a microoxic environment for the nitrogenase enzyme during diazotrophic growth.

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 ...
