π−π Interactions Affect Coordination Geometries [PDF]

open access: yes, 2016
We explore the effect of π−π interactions in the complexes of mercury halides containing the N-(naphthyl)-2-pyrazine carboxamide ligand (L1) in the coordination geometry of the central metal. Results show molecular packing features have a dramatic effect

Applications of Computational Protein Design [PDF]

open access: yes, 2006
Computational protein design determines the amino acid sequence(s) that will adopt a desired fold. It allows the sampling of a large sequence space in a short amount of time compared to experimental methods.

The effect of hydrogen bonding on the π depletion and the π-π stacking interaction [PDF]

open access: yes
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 ...

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

open access: yesFEBS 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 ...

4-(4-Chlorophenyl)-1,2,3-selenadiazole

open access: yesIUCrData, 2018
In the title compound, C8H5ClN2Se, the dihedral angle between the planes of the selenadiazole and chlorophenyl rings is 16.6 (2)°. In the crystal, the packing of the molecules is consolidated by weak C—H...N hydrogen bonds, which generate [001] chains ...
