Carbon nitride quantum dots decorated with cyano groups for boosting photocatalytic hydrogen peroxide production

Green Energy & Environment
The photocatalytic hydrogen peroxide (H2O2) production by graphitic carbon nitride is a sustainable and environment-benign alternative approach of conventional anthraquinone autoxidation technology, but it is great challenges to promote two-electron O2 ...

(4Z)-4-(2-Oxopropylidene)-1,3-bis(prop-2-en-1-yl)-2,3,4,5-tetrahydro-1H-1,5-benzodiazepin-2-one

IUCrData, 2017
In the title compound, C18H20N2O2, the diazepin-2-one ring adopts a tub conformation. The conformation of the acetyl group is partially determined by an intramolecular N—H...O hydrogen bond.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Crystal structure of fenclorim

Acta Crystallographica Section E Crystallographic Communications, 2015
In the title compound, C10H6Cl2N2(systematic name: 4,6-dichloro-2-phenylpyrimidine), which is used commercially as the herbicide safener, fenclorim, the dihedral angle between the dichloropyrimidyl and phenyl rings is 9.45 (10)°. In the crystal, C—H...N hydrogen bonds link adjacent molecules, forming chains along thec-axis direction.

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

FEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Electron transfer between complexes III and IV in S. cerevisiae mitochondrial membranes

FEBS Letters, EarlyView.
Mitochondrial oxidative phosphorylation in S. cerevisiae mitoplasts is limited by complex IV catalytic capacity, rather than two‐dimensional cytochrome c diffusion. At physiological cytochrome c : supercomplex ratios at salinity equivalent to that of 20 mm monovalent salt, activity is maximized, indicating that this low ionic strength accurately mimics

Crystal structure of binase does not reflect its native conformation

Учёные записки Казанского университета: Серия Естественные науки, 2018
Cytotoxic ribonucleases (RNases) of the T1 family, including binase, the secreted guanyl-preferring RNase of Bacillus pumilus, are considered as promising agents of alternative anticancer chemotherapy.
