In-house low-resolution X-ray crystallography.
It is demonstrated that standard in-house protein crystal X-ray diffraction apparatus can be used to measure very low resolution reflections with only a few modifications. The apparatus and modifications are described in detail and tested on two different macromolecular crystal samples: lysozyme and the 30S ribosomal subunit. Contrast-variation measurements on tetragonal hen egg-white lysozyme ...
متن کاملDevelopments in low-resolution biological X-ray crystallography
Despite the recent substantial technological developments in X-ray crystallography, solving and refining structures at low resolutions remain substantial challenges. Many macromolecular crystals, especially those of large molecules or multicomponent assemblies, diffract X-rays to resolutions that are worse than 3.5Å. This report summarizes several recent advances aiding low resolution crystallo...
متن کاملThe X-ray Transform and its Application in Nano Crystallography
In this article a review on the definition of the X- ray transform and some ofits applications in Nano crystallography is presented. We shall show that the X- raytransform is a special case of the Radon transform on homogeneous spaces when thetopological group E(n)- the Euclidean group - acts on ℝ2 transitively. First someproperties of the Radon transform are investigated then the relationship ...
متن کاملReview x Ray crystallography
x Ray crystallography is currently the most favoured technique for structure determination of proteins and biological macromolecules. Increasingly, those interested in all branches of the biological sciences require structural information to shed light on previously unanswered questions. Furthermore, the availability of a protein structure can provide a more detailed focus for future research. ...
متن کاملNew Atomicity-Exploiting Algorithms for Super-Resolution X-Ray Crystallography
The X-ray crystallography problem is to reconstruct a crystalline structure from the Fourier magnitude of its diffracted scattering data. This has three major difficulties: (1) Only Fourier magnitude (not phase) data are known; (2) There is no support constraint (since the crystal is periodic); and (3) only low-wavenumber scattering data are available. But it also has two major advantages: (1) ...
