Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

FEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

FEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

Two-stage oxidation of petrogenic organic carbon in a rapidly exhuming small mountainous catchment

Communications Earth & Environment
Globally, the oxidative flux of petrogenic organic carbon rivals the drawdown by silicate weathering and burial of biospheric carbon. Where and how petrogenic organic carbon is susceptible to degradation along the short-path river-marine continuum in ...

In-depth characterisation of organic matter thermal lability and composition from Arctic Permafrost thaw slumps [PDF]

Biogeosciences
The rapid warming of the Arctic is accelerating permafrost thaw and mobilising large, previously frozen organic-carbon reservoirs. Retrogressive thaw slumps (RTS) are dynamic hotspots of abrupt permafrost disturbance that expose deep, millennial-aged ...

Evolution‐guided yeast complementation reveals functional differences in human PSPH variants

FEBS Open Bio, EarlyView.
Ancient genomes can help guide which human genetic variants are tested experimentally. This study applies that idea to PSPH, a gene involved in serine biosynthesis, and uses high‐throughput yeast complementation to compare variant function. The findings reveal measurable differences among selected alleles and illustrate the value of evolution‐guided ...

Effect of a Rigid Gas Diffusion Media Applied as Distributor of Reagents in a PEMFC in Operation, Part I: Dry Gases.

International Journal of Electrochemical Science, 2009
Several mass transport phenomena develop during the operation of a PEMFC, each one of this generates a mechanical-physics resistance to some extent, implying limitations during operation.

Identifying and characterising a plant GH1 β‐glucosidase that exhibits hydrolytic activity on N‐linked glucopyranoside

FEBS Open Bio, EarlyView.
We report the first β‐glucosidase with demonstrated hydrolytic activity on an N‐linked glycopyranoside. The enzyme, native to maize, was biochemically characterised for this novel reaction, and structural modelling of the enzyme–substrate complex revealed several clues to the underlying reduced catalytic rate relative to its native O‐glycopyranoside ...

An investigation into the effect of Coronavirus‐2019 (SARS‐CoV‐2) on active transportation as an opportunity to develop a sustainable tourist destination in the postpandemic era with an emphasis on the local community (Case study: Dorood City, Lorestan Province, Iran)

Юг России: экология, развитие
The aim of this study is structural modeling of the impact of the coronavirus pandemic on active post‐pandemic transport in Dorood City, Iran, emphasising both tourism and development of a long‐term tourist market through the promotion of low‐carbon ...

Structural studies and functional engineering of NanX: an anhydro‐sialic acid transporter from Escherichia coli

FEBS Open Bio, EarlyView.
Biophysical characterisation shows that NanX, a membrane transport protein from the major facilitator superfamily (MFS), forms both monomers and dimers after purification. AlphaFold modelling and substrate docking provide information on residues likely involved in substrate recognition for NanX and another MFS member, NanT.
