To date crystal structures have been determined for nearly all the elements. Most of them crystallize in a few simple structures and are therefore conveniently treated together. The most common structures are the Cu-type (face-centred cubic) structure, the W-type (body-centred cubic) structure,...

These elements may transmit the substrate-induced conformational change of the substrate binding loop from one subunit to the others in the tetrameric complex and thus mediate the cooperative behavior of PED. 展开 关键词: Bacteria Escherichia coli NAD Oxidoreductases Crystallography, X-Ray Base ...
Once the atomic positions are roughly known, we can approximate the structure by placing at these points isolated atoms of corresponding elements with ideal spherical symmetry and the radial distribution of electron density calculated by quantum-mechanical methods. The structure factors of such ‘procry...

Both histone/histone and histone/DNA interactions depend on the histone fold domains and additional, well ordered structure elements extending from this motif. Histone amino-terminal tails pass over and between the gyres of the DNA superhelix to contact neighbouring particles. The lack of uniformity ...
