The use of longer X-ray wavelengths in macromolecular crystallography for sulfur SAD structure determination

Albocycline: structure determination by x-ray crystallography.

The structure and absolute configuration of the macrolide antibiotic albocycline (1a) has been determined by X-ray crystallographic analysis on the derived p-bromobenzoate (1b). The absolute configuration of albocycline is 4R, 7S, 12S, 13R.

Temperature-dependent macromolecular X-ray crystallography

X-ray crystallography provides structural details of biological macromolecules. Whereas routine data are collected close to 100 K in order to mitigate radiation damage, more exotic temperature-controlled experiments in a broader temperature range from 15 K to room temperature can provide both dynamical and structural insights. Here, the dynamical behaviour of crystalline macromolecules and thei...

The 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 ...
