Peptide‐based ligand antagonists block a Vibrio cholerae adhesin

open access: yesFEBS Letters, EarlyView.
The structure of a peptide‐binding domain of the Vibrio cholerae adhesin FrhA was solved by X‐ray crystallography, revealing how the inhibitory peptide AGYTD binds tightly at its Ca2+‐coordinated pocket. Structure‐guided design incorporating D‐amino acids enhanced binding affinity, providing a foundation for developing anti‐adhesion therapeutics ...

Les couleurs de Moscou et de Saint-Pétersbourg

open access: yesBulletin du Centre de Recherche du Château de Versailles, 2002
Moscow and Saint Petersburg experienced similar evolutions in colour, but the differences in their plans, urbanity and cultural influences, and their alternating roles as capitals, determined the particularities of their palettes.

Highly thermostable mixed lanthanide organic frameworks with high quantum yield for warm white light-emitting diodes

open access: yesFrontiers in Chemistry, 2023
A mixed lanthanide organic framework was prepared via hydrothermal methods using m-phthalic acid (m-H2BDC), 1,10-phenanthroline (1,10-Phen), and Ln3+ ions, formulated as [HNMe2][Eu0.095Tb1.905(m-BDC)3(phen)2] (ZTU-6). The structure and stability of ZTU-6

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

open access: yesFEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

open access: yesFEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Reduction of colour in treated wastewater from textile industry using sawdusts as bio-sorbents

open access: yesTropical Agricultural Research, 2015
Textile industries use dye such as Rhodamine B, Brilliant Red and Reactive Orange for the fabrics. Thus the colour of the effluent even after the normal treatment is not within the standard to discharge into the environment.

Age-related change in carotenoid-based plumage of the American redstart (Setophaga ruticilla) [PDF]

open access: yes, 2013
Plumage colouration serves a variety of functions for birds, including signalling conspecifics, crypsis, and predator-prey interactions. Though much research has been conducted on colour change in species which exhibit delayed plumage maturation, where ...

Substrate specificity of Burkholderia pseudomallei multidrug transporters is influenced by the hydrophilic patch in the substrate‐binding pocket

open access: yesFEBS Letters, EarlyView.
Multidrug transporters BpeB and BpeF from the Gram‐negative pathogen Burkholderia pseudomallei have a hydrophilic patch in their substrate‐binding pocket. Drug susceptibility tests and growth curve analyses using an Escherichia coli recombinant expression system revealed that the hydrophilic patches of BpeB and BpeF are involved in the substrate ...

Colour Perception and Visitor Experiences of Urban Parks as Influenced by an Intense Colourful Urban Artefact: An In-situ Quasi-experiment

open access: yesIconarp International Journal of Architecture and Planning, 2021
Purpose Colourful street furniture, fitness and playground equipment has become increasingly common in contemporary urban green spaces. The study aims to increase knowledge about their influence on human perception of urban park settings, and explore ...
