^aNMR values are averages derived from 10 NMR structures per sequence obtained in the group using standard refinement protocol.

^bNMR values correspond to the NMR ensemble refined with BSC1.

^cNMR values correspond to the NMR ensemble refined with BSC0_OL15.

^d The values were obtained combining the X-Ray structures with PDB codes: 1BNA, 2BNA, 7BNA and 9BNA.
