Ubiquitous Nature of Fluoroquinolones: The Oscillation between Antibacterial and Anticancer Activities

Antibiotics, 2017
Fluoroquinolones are synthetic antibacterial agents that stabilize the ternary complex of prokaryotic topoisomerase II enzymes (gyrase and Topo IV), leading to extensive DNA fragmentation and bacteria death.

Hydrogen‐Producing Catalysts Based on Ferredoxin Scaffolds

Advanced Science, EarlyView.
Selected plant‐type ferredoxins that lack their natural [2Fe‐2S] clusters functionally bind a hydrogenase active site cofactor and act as hydrogenases themselves. In combination with photosystem I, the light‐dependent H₂ evolution almost matches the H₂ production rates of the natural system.

TCMD: A High‐Throughput and Rapid Method for Screening Antimicrobial Ingredients from Renewable Bio‐Based Resources

Advanced Science, EarlyView.
This study develops a strategy to screen the active compounds from bio‐mixtures via combining transcriptomic profiling and molecular docking. The proposed method demonstrates 100% correction in three different biobased mixtures and is 3–20 times faster than traditional approaches.

The Iron–Sulfur Cluster of Bacterioferritin‐Associated Ferredoxin (Bfd): a “Biological Fuse” that Prevents Oxidative Damage to Cells?

Angewandte Chemie, EarlyView.
When cellular iron is low, bacterioferritin (Bfr) releases its stored iron through a reductive process dependent on the [2Fe–2S] ferredoxin Bfd. Why accessing stored iron should depend on an iron‐requiring protein when iron is scarce is unclear. Here, we show that the Bfd [2Fe–2S] cluster is sensitive to oxidative stress, suggesting that it may act as ...

Fast pH‐Driven Solubilization Method of Realgar (As4S4) to Reduce the Toxicity of Arsenic [As(III)] for Medicinal Purposes

Advanced Science, EarlyView.
Arsenic trioxide transformed acute promyelocytic leukemia therapy and shows promise against HIV. A new method to solubilize the mineral realgar produces different arsenic species depleting the main arsenic target, nuclear PML protein, and retaining effects on leukemic and HIV reservoir cells, while minimizing off‐target damage.

Isolation of a member of the candidate phylum ‘Atribacteria’ reveals a unique cell membrane structure

Nature Communications, 2020
A key feature that differentiates prokaryotic cells from eukaryotes is the absence of an intracellular membrane surrounding the chromosomal DNA. Here, the authors isolate a member of the ubiquitous, yet-to-be-cultivated bacterial phylum ‘Candidatus ...
