(a–d) Four hexahydrated Mg2+ ions inside the major grooves of a tRNA structure (PDB: 1TRA). Each ion is stabilized by a hydrogen bond network between the hexahydrated Mg2+ ions and the RNA. The nucleotides of RNA are represented by the backbone model. The spheres represent Mg2+ ions. To see this figure in color, go online.
