Ferredoxin-1 mRNA is destabilized by changes in photosynthetic electron transport [PDF]

Proceedings of the National Academy of Sciences, 1998
In transgenic tobacco, pea Ferredoxin-1 ( Fed-1 ) mRNA accumulates rapidly in response to photosynthesis even when the transgene is driven by a constitutive promoter. To investigate the role of photosynthesis on Fed-1 mRNA stability, we used the tetracycline repressible Top10 promoter system ...

Ferredoxin 1 regulates granulosa cell apoptosis and autophagy in polycystic ovary syndrome

Clinical Science, 2023
Abstract Polycystic ovary syndrome (PCOS), a common reproductive endocrine disorder in women of reproductive age, causes anovulatory infertility. Increased apoptosis of granulosa cells has been identified as one of the key factors contributing to abnormal follicular development.

Structure of the atypical bacteriocin pectocin M2 implies a novel mechanism of protein uptake [PDF]

, 2014
The colicin-like bacteriocins are potent protein antibiotics that have evolved to efficiently cross the outer membrane of Gram-negative bacteria by parasitizing nutrient uptake systems.

Crystal structure of higher plant heme oxygenase-1 and its mechanism of interaction with ferredoxin [PDF]

Journal of Biological Chemistry, 2021
Heme oxygenase (HO) converts heme to carbon monoxide, biliverdin, and free iron, products that are essential in cellular redox signaling and iron recycling. In higher plants, HO is also involved in the biosynthesis of photoreceptor pigment precursors. Despite many common enzymatic reactions, the amino acid sequence identity between plant-type and other

Side chain hydroxylation of C27-steroids and vitamin D3 by a cytochrome P-450 enzyme system isolated from human liver mitochondria

Journal of Lipid Research, 1981
The present study was undertaken to obtain information on the involvement of cytochrome P-450 in the 26-hydroxylation on bile acid intermediates and in the 25-hydroxylation of vitamin D3 in human liver mitochondria.

Identification of ferredoxin II as a major calcium binding protein in the nitrogen-fixing symbiotic bacterium Mesorhizobium loti [PDF]

, 2015
BACKGROUND: Legumes establish with rhizobial bacteria a nitrogen-fixing symbiosis which is of the utmost importance for both plant nutrition and a sustainable agriculture.

Growth- and substrate-dependent transcription of formate dehydrogenase and hydrogenase coding genes in Syntrophobacter fumaroxidans and Methanospirillum hungatei [PDF]

, 2011
Transcription of genes coding for formate dehydrogenases (fdh genes) and hydrogenases (hyd genes) in Syntrophobacter fumaroxidans and Methanospirillum hungatei was studied following growth under different conditions.

Towards the spatial resolution of metalloprotein charge states by detailed modeling of XFEL crystallographic diffraction. [PDF]

, 2020
Oxidation states of individual metal atoms within a metalloprotein can be assigned by examining X-ray absorption edges, which shift to higher energy for progressively more positive valence numbers.

Both human ferredoxins 1 and 2 and ferredoxin reductase are important for iron-sulfur cluster biogenesis

Biochimica et Biophysica Acta (BBA) - Molecular Cell Research, 2012
Ferredoxins are iron-sulfur proteins that have been studied for decades because of their role in facilitating the monooxygenase reactions catalyzed by p450 enzymes. More recently, studies in bacteria and yeast have demonstrated important roles for ferredoxin and ferredoxin reductase in iron-sulfur cluster assembly.

Fine tuning of spatial arrangement of enzymes in a PCNA-mediated multienzyme complex using a rigid poly-L-proline linker. [PDF]

PLoS ONE, 2013
Inspired by natural multienzyme complexes, many types of artificial multienzyme complexes have recently been constructed. We previously constructed a self-assembled complex of a bacterial cytochrome P450 and its ferredoxin and ferredoxin reductase ...
