The [Mg2+]-dependence of the Mg2+ and Na+ (or K+) binding fractions per nucleotide for four different test systems: 80-nt RNA duplex (A-form helix) with 10mM Na+, 76-nt yeast tRNAPhe (PDB ID: 1TRA79) with 32 mM Na+, and 58-nt fragment of rRNA (PDB ID: 1HC881) with 20 and 60 mM K+, respectively. The experimental data are from the References 82–84, respectively.
