Canonical coordinates based on ribose carbon shifts of s2m. (A) Each square corresponds to a can1*/can2* combination of 1 nt derived from its ribose 13C chemical shifts. Specific nucleotides are annotated. Red squares indicate C2′ endo and black squares indicate C3′ endo conformation. Loop and internal loop nucleotides are annotated. (B) Secondary structure of s2m Delta.
