Statistics for order matrix analysis of RDCs measured in the two stems of TAR as a function of Mg2+ concentration

Stem No. RDCs CN RMSD (Hz) RMSDN (Hz) × 103 R
TAR(free)stem I 18 2.5 1.9 3.7 0.99
TAR(free)stem II 22 2.3 2.6 3.0 0.98
TAR(3.0 Mg)stem I 17 2.5 3.9 3.7 0.94
TAR(3.0 Mg)stem II 11 3.3 2.8 2.5 0.98
TAR(4.5 Mg)stem I 16 5.9 4.5 3.9 0.94
TAR(4.5 Mg)stem II 16 2.8 4.0 3.4 0.97

Shown are the total number of RDCs employed in the order matrix analysis (No. RDCs), resulting condition numbers (CN) defined as the ratio of the largest to smallest singular value in the singular value decomposition, root mean square deviation between experimental RDCs and values calculated using best fit order tensor parameters (RMSD), RMSD values normalized for degree of alignment (RMSD (Hz)/ϑ), and correlation coefficient between measured and predicted RDCs (R). Parameters are reported using input coordinates from idealized A-form RNA duplexes. Note that variations in stem-specific RMSD values correlate with the observed degree of alignment, such that RMSDN values are more uniform across the stems.
