Serial X-ray Crystallography [PDF]
Crystals, 2022 Serial crystallography (SX) is an emerging technique to determine macromolecules at room temperature. SX with a pump–probe experiment provides the time-resolved dynamics of target molecules. SX has developed rapidly over the past decade as a technique that not only provides room-temperature structures with biomolecules, but also has the ability to time-

Quantitative Imaging of Single, Unstained Viruses with Coherent X-rays
, 2008 Since Perutz, Kendrew and colleagues unveiled the structure of hemoglobin and myoglobin based on X-ray diffraction analysis in the 1950s, X-ray crystallography has become the primary methodology used to determine the 3D structure of macromolecules ...

Regio-selective substitution at the 1,3- and 6,8-positions of pyrene for the construction of small dipolar molecules [PDF]
, 2015 © 2015 American Chemical Society. This article presents a novel asymmetrical functionalization strategy for the construction of dipolar molecules via efficient regioselective functionalization along the Z-axis of pyrene at both the 1,3- and 6,8-positions.

International Journal of Molecular Sciences, 2018 Protein structural biology came a long way since the determination of the first three-dimensional structure of myoglobin about six decades ago. Across this period, X-ray crystallography was the most important experimental method for gaining atomic ...

X-ray crystallography of krinovite [PDF]
Zeitschrift für Kristallographie, 1972 The unit cell of the meteoritic mineral krinovite, NaMg2CrSia01o, is triclinic with a = 10.22, b = 10.67, c = 8.80 A, IX = 10508', {l =. 960 36', y = 12501'. The monoclinic unit cell given by OLSEN and FUCHS is one of the possible pseudomonoclinic cells.

Hydrogen atoms can be located accurately and precisely by x-ray crystallography
Science Advances, 2016 Hydrogen atoms cannot hide from x-rays anymore but can instead be detected very reliably in routine measurements. Precise and accurate structural information on hydrogen atoms is crucial to the study of energies of interactions important for crystal ...

A nucleotide‐independent, pan‐RAS‐targeted DARPin elicits anti‐tumor activity in a multimodal manner
Molecular Oncology, EarlyView.We report a Designed Ankyrin Repeat Protein that binds and inhibits RAS proteins, which serve as central cell signaling hubs and are essential for the progression of many cancers. Its unique feature is that it does not discriminate between different RAS isoforms or mutations and is capable of binding to RAS in both its active (GTP‐bound) and inactive ...

Structural and functional characterization of chitinase from carnivorous plant Drosera adelae
FEBS Open Bio, EarlyView.A class I chitinase from the carnivorous plant Drosera adelae was expressed and purified using a yeast system, revealing high enzymatic activity. Structural analyses of the catalytic and chitin‐binding domains identified key tyrosine residues involved in substrate binding, offering insights into the enzyme's adaptation for insect digestion.
