Functional analysis of the whole CYPome and Fdxome of Streptomyces venezuelae ATCC 15439

Engineering Microbiology
Cytochrome P450 enzymes (CYPs or P450s) and ferredoxins (Fdxs) are ubiquitously distributed in all domains of life. Bacterial P450s are capable of catalyzing various oxidative reactions with two electrons usually donated by Fdxs.

Phycocyanobilin biosynthesis in Galdieria sulphuraria requires isomerization of phycoerythrobilin synthesized by bilin reductases

The FEBS Journal, EarlyView.
The biosynthesis of bilins, tetrapyrroles essential for light harvesting and sensing, is performed by specific enzymes (FDBRs). In Galdieria sulphuraria, both phycobiliprotein types bind phycocyanobilin, despite lacking the canonical synthesizing gene PCYA. Instead, PEBA and PEBB are encoded, producing phycoerythrobilin, proposed to be later isomerized

The genetic basis of energy conservation in the sulfate-reducing bacterium Desulfovibrio alaskensis G20. [PDF]

, 2014
Sulfate-reducing bacteria play major roles in the global carbon and sulfur cycles, but it remains unclear how reducing sulfate yields energy. To determine the genetic basis of energy conservation, we measured the fitness of thousands of pooled mutants of

Interplay between high‐energy quenching and state transitions in Chlamydomonas reinhardtii: a single‐cell approach

New Phytologist, EarlyView.
Summary Studying cell‐to‐cell heterogeneity is essential to understand how unicellular organisms respond to stresses. We introduce a single‐cell analysis framework that enables the study of intercellular heterogeneity of photosynthetic traits, particularly their interactions within individual cells that have identical genotypes, cellular contexts and ...

Conditional essentiality of the 11-subunit complex I-like enzyme in strict anaerobes: the case of Desulfitobacterium hafniense strain DCB-2

Frontiers in Microbiology
In oxidative phosphorylation, respiratory complex I serves as an entry point in the electron transport chain for electrons generated in catabolic processes in the form of NADH.

Simultaneous Imaging of Cu+ and Cu2+ in Neural Cells Using DNAzyme Probes Reveals Mechanistic Link Between Copper Redox Imbalance and Amyloid Pathology

Angewandte Chemie, Volume 138, Issue 14, 27 March 2026.
We develop Cu+‐ and Cu2+‐specific DNAzyme fluorescent probes to visualize both copper redox states in living neurons. Aβ oligomers cause intracellular copper overload, triggering FDX1 dependent cuproptosis and generating ROS. This work links copper redox imbalance with Aβ pathology and offers a selective, sensitive way to monitor copper homeostasis in ...

An atlas of plant selenium metabolism

New Phytologist, EarlyView.
Summary Selenium (Se) is not only a rare and toxic element but also an essential micronutrient for humans and animals that is often in short supply. Terrestrial plants do not require Se, but it can have growth‐promoting or negative effects, depending on the exposure level.

Molecular dynamics of photosynthetic electron flow in a biophotovoltaic system

Environmental Science and Ecotechnology
Biophotovoltaics (BPV) represents an innovative biohybrid technology that couples electrochemistry with oxygenic photosynthetic microbes to harness solar energy and convert it into electricity. Central to BPV systems is the ability of microbes to perform

Iron Regulation in Clostridioides difficile

Frontiers in Microbiology, 2018
The response to iron limitation of several bacteria is regulated by the ferric uptake regulator (Fur). The Fur-regulated transcriptional, translational and metabolic networks of the Gram-positive, pathogen Clostridioides difficile were investigated by a ...
