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

open access: yes, 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.

A loop unique to ferredoxin-dependent glutamate synthases is not absolutely essential for ferredoxin-dependent catalytic activity [PDF]

open access: yes, 2015
It had been proposed that a loop, typically containing 26 or 27 amino acids, which is only present in monomeric, ferredoxin-dependent, “plant-type” glutamate synthases and is absent from the catalytic α-subunits of both NADPH-dependent, heterodimeric ...

Cuproptosis mediates copper-induced testicular spermatogenic cell death

open access: yesAsian Journal of Andrology
Cuproptosis, a novel mechanism of programmed cell death, has not been fully explored in the context of spermatogenic cells. This study investigated the potential involvement of cuproptosis in spermatogenic cell death using a mouse model of copper ...

Nondenaturing procedure for rapid preparation of ferredoxin from Clostridium pasteurianum [PDF]

open access: yes, 1971
A procedure is described for the rapid preparation of ferredoxin in high yield from crude extracts of C. pasteurianum. The method involves two successive chromatographic treatments on DEAE-cellulose in concentrated ammonium sulfate.

Cytochrome P450-catalyzed allylic oxidation of pentalenene to 1-deoxypentalenic acid in pentalenolactone biosynthesis

open access: yesEngineering Microbiology
Pentalenolactone is a sesquiterpene antibiotic from Streptomyces. Its biosynthetic pathway has been elucidated, except for the oxidation of pentalen-13-al to 1-deoxypentalenic acid.
