NsrR from Streptomyces coelicolor is a nitric oxide-sensing [4Fe-4S] cluster protein with a specialized regulatory function [PDF]

, 2015
The Rrf2 family transcription factor NsrR controls expression of genes in a wide range of bacteria in response to nitric oxide (NO). The precise form of the NO-sensing module of NsrR is the subject of controversy because NsrR proteins containing either ...

Greater Than the Sum of the Parts: Revisiting the Enhancement Effect in Photosynthesis Using Simulated Sun‐ and Shade‐Light

Plant, Cell &Environment, EarlyView.
ABSTRACT Far‐red light (FR) alone drives photosynthesis poorly, but when combined with shorter wavelengths it enhances photosynthesis beyond the sum of their individual effects—a phenomenon known as the Emerson enhancement effect. This effect is well‐established for narrowband PAR‐FR mixtures, and recent results show it also occurs within broadband ...

A cross-linked complex between ferredoxin and ferredoxin-NADP+ reductase.

Journal of Biological Chemistry, 1984
The water-soluble carbodiimide, N-ethyl-3-(3-dimethylaminopropyl)carbodiimide was found to effectively cross-link ferredoxin to ferredoxin-NADP+ reductase. The covalent complex has a stoichiometry of 1 mol of ferredoxin per mol of the reductase. The flavoprotein moiety of the cross-linked complex maintains most of its diaphorase activity and more ...

The Highly Conserved Cys95 Residue of Fructose‐1,6‐Bisphosphatase 1 Mediates the pH‐Driven Structure and Activity of the Enzyme and Photosynthesis

Plant, Cell &Environment, EarlyView.
ABSTRACT In Arabidopsis, exposure to microbial volatile compounds promotes thiol reduction of the Cys95 residue of the photosynthetic enzyme fructose‐1,6‐bisphosphatase (cFBP1). Although highly conserved in plants, the Cys95 function still remains unknown. We characterised recombinant wild‐type (WT) cFBP1 and a variant (C95S) in which the Cys95 residue

Preliminary X-ray diffraction analysis of YqjH from Escherichia coli: a putative cytoplasmic ferri-siderophore reductase [PDF]

, 2008
YqjH is a cytoplasmic FAD-containing protein from Escherichia coli; based on homology to ViuB of Vibrio cholerae, it potentially acts as a ferri-siderophore reductase.

Simultaneous expression of ferredoxin, ferredoxin reductase and P450 in COS7 cells

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1997
cDNA fragments encoding mouse ferredoxin and ferredoxin reductase were simultaneously introduced into COS7 cells by using an expression vector, pUC-SR alpha plasmid. When using the mitochondrial fraction prepared from the transfected cells, cytochrome-c reductase activity was detected.

The Primary Structure of the Clostridium tartarivorum Ferredoxin, a Heat-stable Ferredoxin

Journal of Biological Chemistry, 1971
The amino acid sequence of the Clostridium tartarivorum ferredoxin was determined to be: Ala-His-Ile-Ile-Thr-Asp-Glu-Cys-Ile-Ser-Cys-Gly-Ala-Cys-Ala-Ala-Glu-Cys-Pro-Val-Glu-Ala-Ile-His-Glu-Gly-Thr-Gly-Lys-Tyr-Gln-Val-Asp-Ala-Asp-Thr-Cys-Ile-Asp-Cys-Gly-Ala-Cys-Gln-Ala-Val-Cys-Pro-Thr-Gly-Ala-Val-Lys-Ala-Glu. The first 23 residues were determined in the

Diallyl Trisulfide From Garlic Regulates RAB18 Phase Separation to Inhibit Lipophagy and Induce Cuproptosis in Hepatic Stellate Cells for Antifibrotic Effects

Advanced Science, Volume 12, Issue 21, June 5, 2025.
Diallyl trisulfides (DATs) selectively induce cuproptosis in hepatic stellate cells (HSCs) by targeting Ras‐related protein Rab‐18 (RAB18) and regulating lipophagy. DATs promote RAB18 phase separation, enhance mitochondrial‐associated membrane structures (MAMs) formation, and increase succinylation of dihydrolipoamide dehydrogenase (DLD) at K320.

A Proteomics Profiling Reveals the Neuroprotective Effects of Melatonin on Exogenous β‐amyloid‐42 Induced Mitochondrial Impairment, Intracellular β‐amyloid Accumulation and Tau Hyperphosphorylation in Human SH‐SY5Y Cells

Cell Biology International, Volume 49, Issue 6, Page 659-673, June 2025.
ABSTRACT Alzheimer's disease (AD) is prevalent in the elderly population and characterized by the intracellular accumulation of neurofibrillary tangles (NFTs), composed of tau proteins, and extracellular deposition of beta‐amyloid protein (Aβ). The present study aimed to investigate the neuroprotective effects of melatonin on Aβ42‐induced AD‐like ...

Nonsense Mutations in Rare and Ultra‐Rare Human Disorders: An Overview

IUBMB Life, Volume 77, Issue 6, June 2025.
ABSTRACT Over 7000 rare diseases have been described, collectively affecting 350 million people worldwide. Most of these conditions result from nonsense mutations, representing approximately 10% of all genetic mutations associated with human inherited diseases.
