Improving Whole Biodiversity Monitoring and Discovery With Environmental DNA Metagenomics

Molecular Ecology Resources, EarlyView.
ABSTRACT Environmental DNA (eDNA) metagenomics sequences all DNA molecules present in environmental samples and has the potential of identifying virtually any organism from which they are derived. However, due to unacceptable levels of false positives and negatives, this approach is underexplored as a tool for biodiversity monitoring across the tree of

Antibiotic‐induced decrease of bacterial load in guinea pig intestine reduces α2‐adrenoceptor expression and activity in peristaltic motor inhibition

British Journal of Pharmacology, EarlyView.
Background and Purpose The use of analgosedatives in critically ill patients carries the risk of impairing gastrointestinal (GI) propulsion and could thereby lead to sepsis. The gut microbiota can influence GI motility, but whether GI microbial dysbiosis modifies GI peristalsis impairment by analgosedative drugs has not yet been analysed. This question

Conversion of pyridoxal to pyridoxamine with NH3 and H2 on nickel generates a protometabolic nitrogen shuttle under serpentinizing conditions

The FEBS Journal, EarlyView.
Recent studies show that Ni0 catalyzes amino acid synthesis from 2‐oxoacids via reductive amination. We show that the cofactor pyridoxal is reductively aminated to pyridoxamine, the NH2‐transferring intermediate of transaminations, with NH3 (~ 5 mm) and H2 (5 bar) on Ni0 catalysts within hours in water under serpentinizing hydrothermal vent conditions (

Versatile roles of disordered transcription factor effector domains in transcriptional regulation

The FEBS Journal, EarlyView.
Disordered effector domains (EDs) of transcription factors (TFs) play versatile roles in transcriptional regulation. These include mediating protein–protein interactions with protein complexes like, facilitating condensate formation to enhance transcriptional efficiency, modulating DNA‐binding specificity through genome scanning, and serving as hubs ...
