There is a pressing need for the archiving and curation of raw X-ray diffraction data. This information is critical for validation, methods development and improvement of archived structures. However, the relatively large size of these data...
1.6 angstroms structure of an NAD+-dependent quinate dehydrogenase from Corynebacterium glutamicum [0.03%]

To date, three different functional classes of bacterial shikimate/quinate dehydrogenases have been identified and are referred to as AroE, SDH-L and YdiB. The enzyme AroE and the catalytically much slower SDH-L clearly prefer NADP+/NADPH a...
Structure determination of an anti-HIV-1 Fab 447-52D-peptide complex from an epitaxially twinned data set [0.03%]
