Crystallography on a chip [PDF]

Acta Crystallographica Section D Biological Crystallography, 2012
A new chip-based crystal-mounting approach for rapid room-temperature data collection from numerous crystals is described. This work was motivated by the recent development of X-ray free-electron lasers. These novel sources deliver very intense femtosecond X-ray pulses that promise to yield high-resolution diffraction data of nanocrystals before their ...

Semax, a Copper Chelator Peptide, Decreases the Cu(II)-Catalyzed ROS Production and Cytotoxicity of aβ by Metal Ion Stripping and Redox Silencing

Bioinorganic Chemistry and Applications
Alzheimer’s disease (AD) is the most common neurodegenerative disorder associated with cognitive decline and loss of memory. It is postulated that the generation of reactive oxygen species (ROS) in Fenton-like reaction connected with Cu(II)/Cu(I) redox ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

X-ray-Induced Heating in the Vicinity of the X-ray Interaction Point

Applied Sciences, 2023
When X-rays pass through a material, radiation damage occurs, and heat is generated at the X-ray interaction point, which can then be transferred around the X-ray irradiation site. This X-ray-induced heat transfer can affect the temperature of the sample

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 ...

CELLOPT: improved unit-cell parameters for electron diffraction data of small-molecule crystals [PDF]

, 2022
Electron diffraction enables structure determination of organic small molecules using crystals that are too small for conventional X-ray crystallography. However, because of uncertainties in the experimental parameters, notably the detector distance, the

The Effect of the Position of the Pyridine Nitrogen Atom in the Tridentate NN'O Schiff Base Ligand on the Type of Coordination Polymer of the Copper(II) Complex: A Crystallographic Study [PDF]

شیمی کاربردی روز
Coordination polymers (CPs) are synthesized using bridging organic ligands and metal ions, depending on the geometric coordination of the metal, the bridging ligands, and the donor atoms present in these ligands, various one-, two-, or three-dimensional ...
