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 ...

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.

FEBS Letters, EarlyView.An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Acta Crystallographica Section E: Crystallographic Communications, 2016 The title coordination polymer, [Ni(C7H3NO4)(C4H4N2)(C2H6OS)]n, consists of [010] chains composed of NiII ions linked by bis-monodentate-bridging pyrazine molecules. Each of the two crystallographically distinct NiII ions is located on a mirror plane and

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.

A Preliminary Investigation of the Additivity of π−π or π+−π Stacking and T-Shaped Interactions between Natural or Damaged DNA Nucleobases and Histidine [PDF]
, 2016 Previous computational studies have examined π−π and π+−π stacking and T-shaped interactions in nucleobase−amino acid dimers, yet it is important to investigate how additional amino acids affect these interactions since simultaneous contacts often appear

Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function
FEBS Open Bio, EarlyView.We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...

A dibenzofuran derivative: 2-(pentyloxy)dibenzo[b,d]furan
IUCrData, 2018 The title compound, C17H18O2, crystallizes in two-dimensional sheets, in which the 2-(pentyloxy)dibenzo[b,d]furan molecules are arranged in a head-to-head and tail-to-tail fashion that enables hydrophobic interactions between fully extended 2-pentoxy ...
