Hydrodynamic models of proteins have been generated by recourse to crystallographic data and applying a filling model strategy in order to predict both hydrodynamic and scattering parameters. The design of accurate protein models retaining the majori

The technique of small-angle scattering can be used advantageously for deriving the shape of proteins in solution. Presently, advancedab initioapproaches allow the reliable automated reconstruction of particle shapes. In particular, the procedures ba

The X-ray damage of the sulfhydryl enzyme malate synthase from yeast has been investigated by physicochemical studies including time-resolved small-angle X-ray scattering. Our previous studies already suggested the role of cysteine-sulfenic acid and

The reconstruction of sphere shells as realized in bacteriophage capsids can be achieved by ab initio modelling approaches based on a genetic algorithm or simulated annealing. The application of tight constraints such as icosahedral symmetry makes th

The growing interest in the natural zeolite is based on some specific peculiarities of its structure, which after dehydration enables adsorption processes of some polymer molecules and/or segments to take place on the zeolite surface. The main goal o

Reconstructions of low-resolution three-dimensional solution structures of proteins from one-dimensional small-angle X-ray scattering (SAXS) data can be achieved by trial-and-error or ab initio approaches. It is demonstrated that all tested advanced

The solution structure of simple and complex proteins can be modeled efficaciously, starting either from solution scattering data or from the 3D structures derived from crystallographic work or from electron microscopy. Best fitting low-resolution be
