Force-Induced Transition of π–π Stacking in a Single Polystyrene Chain [PDF]
, 2019 Although π–π interactions have been studied for several decades, the quantification of the strength of π–π interactions in a macromolecule remains a big challenge.

Anisotropy of π–π Stacking as Basis for Superlubricity [PDF]
When two surfaces move against each other, often high adhesive strength with low friction is desired. Then, the interfacial interaction requires a strong directional anisotropy, as provided by π–π stacking.

The use of a molecular balance derived from 5,5′-bipyrazole to calculate π-π stacking interactions [PDF]
, 2013 Theoretical calculations have been carried out on 3,3′-dimethyl-1,1′-diphenyl-5,5′-bi-1H-pyrazole to evaluate its usefulness as a molecular balance to measure π-π stacking.

Cation-Induced π-Stacking [PDF]
, 2016 The design and synthesis of a new dipyridyl ligand with appended phenanthryl moieties is described. On addition of increments of silver(I) trifluoromethanesulfonate to a solution of the ligand, the phenanthryl protons shift upfield in the 1H NMR spectrum,

The effect of hydrogen bonding on the π depletion and the π-π stacking interaction [PDF]
Non-covalent interactions such as hydrogen bonding and π–π stacking are essential types of interactions governing molecular self-assembly. The π–π stacking ability of aromatic rings depends on the electron density of the π orbitals, which is affected by ...

From Paramagnetic to Superparamagnetic Ionic Liquid/Poly(ionic liquid): The Effect of π–π Stacking Interaction [PDF]
, 2019 Magnetic ionic liquids (MILs) and poly(magnetic ionic liquids) (PMILs) with FeCl4– as anions usually show weak magnetism, such as paramagnetism or antiferromagnetism, at room temperature.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9
FEBS Letters, EarlyView.Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Molecular design of orthogonal stacking system at the complex interface of HtrA PDZ domain with its peptide ligands [PDF]
Journal of the Serbian Chemical Society, 2019 The high temperature requirement A (HtrA) protease plays a crucial role in protein quality control and cell fate. The enzyme contains a catalytic protease domain and a regulatory PDZ domain; the latter determines the substrate specificity of the former ...

FEBS Letters, EarlyView.Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...
