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

FEBS 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 ...

Anisotropic Dynamic Disorder of π‐Stacking and Static Disorder in Organic Electron Transporting Materials with Isomorphic Crystal Structures

Small Structures
In organic semiconductors, charge transport is strongly correlated with intermolecular π–π interactions and the dynamic disorder caused by solid‐state phonon vibrations.

Crystal structure of (μ-N-allylthiourea-κ2S:S)bis[μ-bis(diphenylphosphanyl)methane-κ2P:P′]bis[bromidocopper(I)] acetonitrile disolvate

Acta Crystallographica Section E: Crystallographic Communications, 2015
The reaction of cuprous bromide with a mixture of 1,1-bis(diphenylphosphanyl)methane (dppm: C25H22P2) and N-allylthiourea (ATU: C4H8N2S) in acetonitrile yielded the title solvated dinuclear complex, [Cu2Br2(C4H8N2S)(C25H22P2)2]·2C2H3N or [Cu2Br2(ATU ...

Stacking sensitive topological phases in a bilayer Kane-Mele-Hubbard model at quarter filling

, 2019
Layered quasi two dimensional systems have garnered huge interest both in the advancement of technology and in understanding emergent physics such as unconventional superconductivity, topological phases. In particular, the study of topological properties

Entropy and biological systems: experimentally-investigated entropy-driven stacking of plant photosynthetic membranes [PDF]

, 2014
According to the Second Law of thermodynamics, an overall increase of entropy contributes to the driving force for any physicochemical process, but entropy has seldom been investigated in biological systems.

Conserved structural motifs in PAS, LOV, and CRY proteins regulate circadian rhythms and are therapeutic targets

FEBS Letters, EarlyView.
Cryptochrome and PAS/LOV proteins play intricate roles in circadian clocks where they act as both sensors and mediators of protein–protein interactions. Their ubiquitous presence in signaling networks has positioned them as targets for small‐molecule therapeutics. This review provides a structural introduction to these protein families.

(3Z)-3-Benzylidene-1H-benzimidazo[1,2-a]imidazol-2(3H)-one

IUCrData, 2016
In the title compound, C16H11N3O, the molecular conformation is partially determined by an intramolecular C—H...π(ring) interaction. In the crystal, pairwise N—H...N hydrogen bonds form dimers, which associate into stacks through a combination of C—H...O,

Magnetism of two-dimensional defects in Pd: stacking faults, twin boundaries and surfaces

, 2006
Careful first-principles density functional calculations reveal the importance of hexagonal versus cubic stacking of closed packed planes of Pd as far as local magnetic properties are concerned.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

FEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

4-(4-Bromophenyl)-2-(3-(4-chlorophenyl)-5-{3-[5-methyl-1-(4-methylphenyl)-1H-1,2,3-triazol-4-yl]-1-phenyl-1H-pyrazol-4-yl}-4,5-dihydro-1H-pyrazol-1-yl)thiazole

IUCrData, 2018
In the title compound, C37H28BrClN8O, the linked chlorophenyl, pyrazolyl and thiazolyl ringss are almost coplanar, with dihedral angles of 0.6 (3)° between the chlorophenyl and pyrazolyl rings and 5.4 (3)° between the pyrazolyl and thiazolyl rings.
