1AJF - PubMed Abstract: 
Solvated metal ions are critical for the proper folding and function of RNA. Despite the importance of these ions, the details of specific metal ion-RNA interactions are poorly understood. The crystal structure of a group I intron ribozyme domain characterized several metal-binding sites in the RNA with osmium (III) hexammine bound in the major groove. A corresponding method for locating and characterizing metal-binding sites of RNA in solution is of obvious interest. NMR should be ideal for localizing metal hexammine ions bound to the RNA because of the large concentration of protons around the metal center.
