Crystal structure of 1-methoxypyrene
Acta Crystallographica Section E: Crystallographic Communications, 2015 The title compound, C17H12O, crystallized with three independent molecules (A, B and C) in the asymmetric unit. In the crystal, the three independent molecules are linked by π–π interactions [centroid–centroid distances = 3.551 (3)–3.977 (2) Å], which ...

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?
FEBS Letters, EarlyView.This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

A dispersive study of final-state interactions in $$K\rightarrow \pi \pi \pi $$ K → π π π amplitudes
European Physical Journal C: Particles and FieldsA system of dispersive representations of the Omnès–Khuri–Treiman–Sawyer–Wali type for the final-state interactions in the amplitudes of the $$K\rightarrow \pi \pi \pi $$ K → π π π weak transitions is constructed, under the assumptions that CP and ...

Crystal structure of 2-(3-bromophenyl)-1,3-dithiane
Acta Crystallographica Section E: Crystallographic Communications, 2015 In the title compound, C10H11BrS2, the 1,3-dithiane ring has a chair conformation with the 1,4-disposed C atoms being above and below the remaining four atoms. The bromobenzene ring occupies an equatorial position and forms a dihedral angle of 86.38 (12)°

String-generated quartic scalar interactions [PDF]
, 2000 The {\em cutting and sewing} procedure is used for getting two-loop order Feynman diagrams of $\Phi^{4}$-theory with an internal SU(N) symmetry group, starting from tachyon amplitudes of the open bosonic string theory.

FEBS Letters, EarlyView.Bifidobacterium bifidum establishes symbiosis with infants by metabolizing lacto‐N‐biose I (LNB) from human milk oligosaccharides (HMOs). The extracellular multidomain enzyme LnbB drives this process, releasing LNB via its catalytic glycoside hydrolase family 20 (GH20) lacto‐N‐biosidase domain.

Crystal structure of 10-ethyl-7-(9-ethyl-9H-carbazol-3-yl)-10H-phenothiazine-3-carbaldehyde
Acta Crystallographica Section E: Crystallographic Communications, 2017 The title compound, C29H24N2OS, contains a phenothiazine moiety linked to a planar carbazole unit (r.m.s. deviation = 0.029 Å) by a C—C single bond. The phenothiazine moiety possesses a typical non-planar butterfly structure with a fold angle of 27.36 (9)

, 2004 We discuss the interaction of photons with neutrinos including two lepton loops. The parity violation in the gamma-nu to gamma-nu channel due to two lepton loops is substantially enhanced relative to the one lepton loop contribution.

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