Advanced ensemble modelling of flexible macromolecules using X-ray solution scattering

Dynamic ensembles of macromolecules mediate essential processes in biology. Understanding the mechanisms driving the function and molecular interactions of 'unstructured' and flexible molecules requires alternative approaches to those traditionally employed in structural biology. Small-angle X-ray scattering (SAXS) is an established method for structural characterization of biological macromole...

Small-angle X-ray and neutron scattering by biological macromolecules.

be 35.1 kJ/mol (8.4 kcal/mol) for formation of the complex and 115.9 kJ/mol(27.7 kcal/mol) for dissociation of the complex. The kinetic results, as well as helping to describe and validate the model of hyaluronate-proteoglycan interaction, are also of value in the design of experiments. In the experiment shown in Fig. 1 equilibrium is only attained after approx. 1-lfh, as monitored by light-sca...

Structural analysis of flexible proteins in solution by small angle X-ray scattering combined with crystallography.

In the last few years, SAXS of biological materials has been rapidly evolving and promises to move structural analysis to a new level. Recent innovations in SAXS data analysis allow ab initio shape predictions of proteins in solution. Furthermore, experimental scattering data can be compared to calculated scattering curves from the growing data base of solved structures and also identify aggreg...

Application of small angle X-ray scattering (SAXS) for differentiation between normal and cancerous breast tissues

ABSTRACT Background: Coherent scattering leads to diffraction effects and especially constructive interferences. Theseinterferences carry some information about the molecular structure of the tissue. As breast cancer isthe most widespread cancer in women, this project evaluated the application of small angleX-ray scattering (SAXS) for differentiation between normal and cancerous breast tissues....
