Examples of electron density
Figures from Bernhard Rupp's book "Biomolecular Crystallography" (with permission by the author)Edit
There is more material (all figures, citations, tutorials) at the book's overview page.
You can see the full-size, high-resolution figure by clicking on it.
Cis-peptide bond and its electron densityEdit
Covalently modified residuesEdit
Covalent binding of ligandsEdit
Additives mediating intermolecular contactsEdit
Heavy-atom derivatization of a proteinEdit
The trimeric bacterial outer membrane protein OprPEdit
Chemically modified lysine residue (Dimethyllysine)Edit
Glycosylated residues stabilizing homodimerEdit
Uranium-atom solution and Fourier truncation ripplesEdit
Solvent molecules (water, MPD, Mg2+)Edit
(Pete Dunten had noticed that PDB code 2nls should be 1nls; this is now in the book's errata; the above legend has the correction.)
Split side-chain conformationsEdit
Se-Met residues and chloride ionEdit
