Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Identifying Recruitment Sources Across Trophic Levels in a Large River Food Web

open access: yesEcology and Evolution
Assemblages are connected through the movement of physical and biological resources including recruits. Identifying recruitment sources for predators and their prey could help us understand how assemblages use connectivity across multiple trophic levels ...

Les barrages qui cachent l’eau : l'oubli des vulnérabilités aux inondations lors de l’aménagement de la Dordogne (1917-1935)

open access: yesVertigO, 2016
A series of large hydro-electrical dams was built on the Dordogne River over the course of the twentieth century. Given the historical prevalence of floods in the basin, it is striking to find virtually no mention of flood risk or vulnerability in the ...

Identification of a Shiga toxin A‐derived peptide internalized into Gb3 receptor‐bearing cells via interaction with the Shiga toxin B subunit

open access: yesFEBS Letters, EarlyView.
The process of internalization of the Shiga toxin A subunit via formation of a complex with the Shiga toxin B subunit, which specifically binds to the Gb3 receptor. The peptide is designed to act as a carrier of drugs into cancer cells. Here, we explored the potential of peptides derived from the catalytic A subunit of Shiga toxin (STxA) to be drug ...

Investigating transcription factor dynamics in health and disease using FRAP

open access: yesFEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

Afforestation of common land in the Classical Karst: relations between the authorities, the local population, and the economic consequences of afforestation

open access: yesActa Carsologica
The findings of environmental history are in the service of ecology and represent an important contribution to the understanding of the sustainable management of land. The aim of this article is to shed light on the relations between the local population

Fields: The Transformation and Healing of the Whitewater Valley

open access: yesOpen Rivers, 2018
They say hindsight is 20/20. Farmers of the past didn’t have information about environmentally friendly agricultural techniques. The farming techniques used today to reduce erosion and other negative environmental effects were developed as we learned ...

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

open access: yesFEBS 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.

Utilización de documentos históricos en la reconstrucción de la vegetación de la Llanura de la Travesía (Argentina) a principios del siglo XIX The use of historical documents to reconstruct the vegetation of the Llanura de la Travesía (Argentina) during early nineteenth century

open access: yesRevista Chilena de Historia Natural, 2003
La Llanura de la Travesía se extiende en las provincias de Mendoza y San Luis (Argentina) entre el piedemonte de los Andes y las Sierras Pampeanas. El objetivo de este trabajo fue reconstruir las condiciones ambientales de la Llanura de la Travesía a ...
