SALMON: solvent accessibility, ligand binding, and mapping of ligand orientation by NMR spectroscopy.
|Abstract||Quinone oxidoreductase 2 (NQO2) binds the prodrug tretazicar (also known as CB1954, 5-(aziridin-1-yl)-2,4-dinitrobenzamide), which exhibits a profound antitumor effect in human cancers when administered together with caricotamide. X-ray structure determination allowed for two possible orientations of the ligand. Here we describe a new NMR method, SALMON (solvent accessibility, ligand binding, and mapping of ligand orientation by NMR spectroscopy) ... [truncated at 450 characters in length]|

Structural basis for Par-4 recognition by the SPRY domain- and SOCS box-containing proteins SPSB1, SPSB2, and SPSB4.
|Abstract||The mammalian SPRY domain- and SOCS box-containing proteins, SPSB1 to SPSB4, belong to the SOCS box family of E3 ubiquitin ligases. Substrate recognition sites for the SPRY domain are identified only for human Par-4 (ELNNNL) and for the Drosophila orthologue GUSTAVUS binding to the DEAD-box RNA helicase VASA (DINNNN). To further investigate this consensus motif, we determined the crystal structures of SPSB1, SPSB2, and SPSB4, as well as their bin ... [truncated at 450 characters in length]|
