Three-state NMR solution structure of s2m_omicron. Out of the total 20 structures, nine structures are assigned to state A, five structures to state B, and three structures to state C. The bundles are shown transparent, and one representative is shown in gray with the loop nucleotides in color and annotated. (A + B + C) Aligned loop nucleotide of state A (A), state B (B), and state C (C) with pairwise mean RMSDs of 1.4 ± 0.5, 1.1 ± 0.3, and 2.3 ± 0.5 Å, respectively. (D + E + F) Aligned full NMR structures of state A (D), state B (E), and state C (F) with pairwise mean RMSDs of 2.0 ± 0.5, 2.5 ± 0.9, and 2.3 ± 0.5 Å, respectively. The structure bundle is accessible via the PDB (code: 9QZJ).
