Calorimetric characterization of the stability and activity of trimethylamine‐N‐oxide (TMAO) demethylase from Methylocella silvestris BL2

Protein Science, Volume 34, Issue 11, November 2025.
Abstract Trimethylamine‐N‐oxide (TMAO) is an organic osmolyte found in numerous species and is known to have a range of biological effects. TMAO has recently garnered attention in the medical field due to its association with cardiovascular diseases, underscoring the need for its reliable detection and quantification.

The global anaerobic metabolism regulator fnr is necessary for the degradation of food dyes and drugs by Escherichia coli

mBio, 2023
The microbiome is an underappreciated contributor to intestinal drug metabolism with broad implications for drug efficacy and toxicity. While considerable progress has been made toward identifying the gut bacterial genes and enzymes involved, the role of

Transition Zones at the Changing Coastal Terrestrial‐Aquatic Interface

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 11, November 2025.
Abstract Coastal soils are a significant but highly uncertain component of global biogeochemical cycles. These systems experience spatial and temporal variability in biogeochemical processes, driven by marsh‐to‐upland gradients and hydrological fluctuations.

The yhiM gene codes for an inner membrane protein involved in GABA export in Escherichia coli

AIMS Microbiology, 2017
In order to survive the exposure to acid pH, Escherichia coli activates molecular circuits leading from acid tolerance to extreme acid resistance (AR). The activation of the different circuits involves several global and specific regulators affecting the

NMR Metabolite Profiles of the Bivalve Mollusc Mytilus galloprovincialis Before and After Immune Stimulation With Vibrio splendidus

Frontiers in Molecular Biosciences, 2021
The hemolymph metabolome of Mytilus galloprovincialis injected with live Vibrio splendidus bacteria was analyzed by 1H-NMR spectrometry. Changes in spectral hemolymph profiles were already detected after mussel acclimation (3 days at 18 or 25 °C).

Studies of the membrane‐bound flavocytochrome MsrQ flavin mononucleotide (FMN)‐binding site reveal an unexpected ubiquinone cofactor

The FEBS Journal, Volume 292, Issue 20, Page 5491-5505, October 2025.
The membrane‐bound heme flavoprotein MsrQ is the specific electron donor for the periplasmic methionine sulfoxide reductase MsrP. Analysis of its flavin environment revealed that ubiquinone (UQ) is a cofactor for MsrQ. However, redox studies demonstrate that UQ cannot function as an electron donor for the MsrPQ system.

Photosynthetic and Growth Responses of Arundo donax L. Plantlets Under Different Oxygen Deficiency Stresses and Reoxygenation

Frontiers in Plant Science, 2019
Promotion of nonfood species production to marginal, degraded lands abandoned by mainstream agriculture is affected by extremes of water availability (droughts and floods), which have increased in frequency and intensity and account for severe yield ...

Morphological and Phenological Responses of Eragrostis plana Nees and Eragrostis pilosa (L.) P. Beauv. Plants Subjected to Different Soil Moisture Conditions [PDF]

Planta Daninha, 2019
: Experiments were run in a greenhouse where samples of Eragrostis pilosa and Eragrostis plana, species that infest rice crops, were subjected to three soil moisture conditions (50% of soil water retention capacity (WRC), 100% of WRC, 10 cm water depth),
