GPCR Conformations: Implications for Rational Drug Design

open access: yesPharmaceuticals, 2010
G protein-coupled receptors (GPCRs) comprise a large class of transmembrane proteins that play critical roles in both normal physiology and pathophysiology.

Crystallography in the 21st century [PDF]

open access: yesIUCrJ, 2015
The field of crystallography, which has had a major impact on the sciences in the last 100 years, is continuing to expand scientific horizons as technical and conceptual boundaries are overcome. Structure-function-dynamics will become an integrated theme for many studies as will obtaining structures without the 'benevolent tyranny' of crystals.

Namdinator – automatic molecular dynamics flexible fitting of structural models into cryo-EM and crystallography experimental maps

open access: yesbioRxiv, 2018
Model building into experimental maps is a key element of structural biology, but can be both time consuming and error-prone. Here we present Namdinator, an easy-to-use tool that enables the user to run a Molecular Dynamics Flexible Fitting (MDFF ...

Applications of X-ray Powder Diffraction in Protein Crystallography and Drug Screening

open access: yesCrystals, 2020
Providing fundamental information on intra/intermolecular interactions and physicochemical properties, the three-dimensional structural characterization of biological macromolecules is of extreme importance towards understanding their mechanism of action.

Radiation damage and dose limits in serial synchrotron crystallography at cryo- and room temperatures

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2020
Significance Macromolecular X-ray crystallography (MX) is the most prolific structure determination method in structural biology but is limited by radiation damage.

Amplification of UV radiation and gain mechanisms in ZnO films with loose-packed structure

open access: yesКомпьютерная оптика
The modern demands for miniaturization of optoelectronic devices, in particular, for the UV range, are inextricably linked with the improvement of fabrication technologies for the corresponding photonic nano/micro objects and the study of their radiative

Crystallography on Curved Surfaces

open access: yes, 2006
We study static and dynamical properties that distinguish two dimensional crystals constrained to lie on a curved substrate from their flat space counterparts.

Crystallography for the People [PDF]

open access: yesActa Crystallographica Section A Foundations and Advances, 2013
The British Crystallographic Association (BCA) has engaged in public outreach projects over the past two years, aimed at communicating the basic principles and applications of crystallography to the general public, especially in light of the Bragg Centenary Celebrations and the International Year of Crystallography.
