Non-covalent interaction of boron and nitrogen atoms

Известия высших учебных заведений. Поволжский регион: Физико-математические науки
Background. The calculation of the interaction between boron and nitrogen atoms is interesting from the point of view of predicting physical properties and creating new dielectric materials and carbon-free nanomaterials.

Unraveling pH-dependent peptide conformational transitions via integration of main mechanical forces and side-chain interactions

Frontiers in Chemical Biology
The stability and flexibility of peptide structures are strongly influenced by environmental conditions, particularly pH. In this study, we investigate how changes in protonation states of pH-responsive residues modulate non-covalent interaction networks

The n → π* interaction: a rapidly emerging non-covalent interaction

Physical Chemistry Chemical Physics, 2015
This perspective describes the current status of a recently discovered non-covalent interaction named as the n → π* interaction, which is very weak and counterintuitive in nature.

Synthesis of multimetallic dendrimers through non-covalent interactions [PDF]

Dalton Trans., 2012
Hexa-ammonium functionalized Dendriphos ligands and mono-sulfonate functionalized metal complexes have been used as building blocks for the preparation of multimetallic dendritic assemblies. These metallodendrimers consist of a single metal centre surrounded by an oligocationic shell formed by the coordinated Dendriphos ligands and multiple associated ...

Heterotropic regulation and negative homotropic cooperativity

FEBS Open Bio, EarlyView.
We identified a structural module common to some proteins that couple negative cooperativity with heterotropic regulation, two features that rarely coexist. These proteins are ring‐like and present an ordered asymmetry whereby noncontacting subunits are symmetric, and their tertiary structure differs from that of contacting subunits.

Non-covalent and covalent-synergistical-interaction assembled GO self-supporting membrane with excellent alignment for ultrahigh H2 barrier applications

The emerging graphene oxide membranes (GOm) showcase superiority in molecule barrier applications, yet their hydrogen (H2) barrier performance is still less than ideal due to the insufficient control of GOm assembly architecture.

Avidin is evolutionarily conserved in fish but dispensable for development and resistance against Streptococcus agalactiae in zebrafish

FEBS Open Bio, EarlyView.
The presence of biotin‐binding avidin proteins in fish and their biological significance are poorly characterized. We cataloged fish avidins and demonstrate that they are widely present and evolutionarily conserved. We created avd knockout zebrafish and show that zebavidin is dispensable for development and that resistance of avd knockout embryos in ...

Non-Covalent Interactions Mimic the Covalent: An Electrode-Orthogonal Self-Assembled Layer

, 2023
Charge-transfer events central to energy conversion and storage and molecular sensing occur at electrified interfaces. Synthetic control over the interface is traditionally accessed through electrode-specific covalent tethering of molecules.

Binding of Bezafibrate to Human Serum Albumin: Insight into the Non-Covalent Interaction of an Emerging Contaminant with Biomacromolecules

Molecules, 2012
In recent years, bezafibrate (BZF) has been frequently detected in environmental media. In order to reveal the toxicity of such an emerging pollutant, its interaction with human serum albumin (HSA) was studied by fluorescence spectrometry, circular ...

Salmonella enterica serovar typhi limits the potency of typhoid toxin and ADP‐ribosylating toxin AB to establish a persistent infection

FEBS Open Bio, EarlyView.
The two catalytic subunits of typhoid toxin dissociate from the holotoxin in the ER of an intoxicated cell, but only CdtB exits the ER to generate immunosuppressive effects. PltA is retained in the ER and sequestered from its cytosolic target, thus allowing the anti‐inflammatory effects of CdtB to promote intestinal colonization.
