The strict anaerobe Clostridium ljungdahlii can ferment CO or H2/CO2 via the Wood-Ljungdahl pathway to acetate, ethanol, and 2,3‐butanediol. This ability has attracted considerable interest, since it can be used for syngas fermentation to produce ...

A haloarchaeal ferredoxin electron donor that plays an essential role in nitrate assimilation [PDF]
In the absence of ammonium, many organisms, including the halophilic archaeon Haloferax volcanii DS2 (DM3757), may assimilate inorganic nitrogen from nitrate or nitrite, using a ferredoxin-dependent assimilatory NO3-/NO2- reductase pathway.

Restoration of the mitochondrial Fe–S protein FDX1 suppresses clear cell renal cell carcinoma by coupling ferroptosis with tumor‐intrinsic innate immune activation. FDX1 induces mitochondrial dysfunction and mtDNA/mt‐dsRNA release, activating cGAS–STING and RIG‐I/MDA5–MAVS signaling to elicit type I interferon responses, thereby promoting antigen ...

Heterogeneity of adrenocortical ferredoxin [PDF]
Bovine adrenocortical ferredoxin (adreno‐ferredoxin) was purified from adrenocortical mitochondria by an improved method that included hydrophobic chromatography on Toyopearl gels. The purified ferredoxin was electrophoretically homogeneous. It was further separated into five fractions by hydrophobic chromatography on a TSK‐gel phenyl‐5PW column with a

Heterocyst Thylakoid Bioenergetics
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.

Environmental stress increases the risk of electron accumulation in photosystem I (PSI) of chloroplasts, which can cause oxygen (O2) reduction to superoxide radicals and decreased photosynthetic ability.

Characterisation of components and mechanisms involved in redox-regulation of protein import into chloroplasts [PDF]
The vast majority of chloroplast proteins is encoded in the nucleus and thus has to be posttranslationally imported into the organelle, a process that is facilitated by two multimeric protein machineries, the Toc and Tic complexes (translocon at the ...

A synergistic electron transfer (ET) optimization strategy modulating conformational dynamics, ET pathway, and substrate orientation is proposed for self‐sufficient cytochrome P450s. Guided by this strategy, a P450 variant with improved ET and catalytic efficiency was identified, and the underlying molecular basis was revealed by computational analysis.

Energy Conservation in Fermentations of Anaerobic Bacteria
Anaerobic bacteria ferment carbohydrates and amino acids to obtain energy for growth. Due to the absence of oxygen and other inorganic electron acceptors, the substrate of a fermentation has to serve as electron donor as well as acceptor, which results ...

Photosynthetische Mikroorganismen können zur lichtgetriebenen H2‐Entwicklung genutzt werden. Eine Einschränkung ist jedoch die damit verbundene Bildung von molekularem Sauerstoff als Nebenprodukt der Photosynthese, der die Aktivität des Biokatalysators für die H2‐Produktion, d. h. die Hydrogenase, inhibiert.
