Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

FEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

ANTIMICROBIAL IMPACTS OF SALICORNIA FRUTICOSA PLANT EXTRACTS CULTIVATED UNDER MATROUH GOVERNORATE CONDITIONS, EGYPT [PDF]

Egyptian Journal of Desert Research
Salicornia is one of the halophytes with natural bioactive molecules that exhibit antimicrobial activities. Since microorganisms’ antimicrobial resistance phenomena arise due to acquiring of resistant genes and their transmission through their ...

Translophagy—A potential link between autophagy impairment and translational errors

FEBS Letters, EarlyView.
Neurodegenerative diseases are characterised by the accumulation of abnormal proteins and protein aggregates, but their origin often remains unknown. We propose that selective autophagy removes damaged protein‐making machinery, preventing errors during protein synthesis.

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

FEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Pollen Harvest by Sonoran Desert Honey Bees: Conservation Implications for Native Bees and Flowering Plants

, 1996
Managed and feral honey bee colonies (Apis mellifera) harvest immense quantities of nectar and pollen within kilometers of their nests whether they live in relatively undisturbed or agricultural habitats.

Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers

FEBS Letters, EarlyView.
Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be

POTENTIAL OF SALICORNIA FRUTICOSA AS A FORAGE IN EGYPT: PHYTOCHEMICAL CONSTITUENTS, NUTRITIVE VALUE, AND METHANE PRODUCTION (AN IN VITRO PRELIMINARY STUDY) [PDF]

Egyptian Journal of Desert Research
This study was carried out to investigate the potential of different ecotypes of Salicornia fruticosa to be a forage crop for ruminants. Three different ecotypes of Salicornia as wild, monoculture and intercropped (with tomato plants) were tested in ...

Leucine‐rich glioma inactivated 1 (LGI1) is a ganglioside‐binding protein

FEBS Letters, EarlyView.
Neuronal hyperexcitability associated with a decrease/absence of the extracellular protein LGI1 has been suggested to be primarily due to the downregulation of Kv1 channel expression. The molecular mechanisms underlying this decrease have not yet been elucidated.
