Figure 1
Illustration of the geometry terms [dihedral angle dihP(i, j) (a), distance disP(i, j) (b) and angle angP(i, j) (c)] included in CSSR score calculation for nucleotide pair i and j in an input RNA structure with only a P atom. Each `P' in the upper panels represents the P atom of a single nucleotide; a solid black bar connecting two P atoms means the two nucleotides are adjacent nucleotides in the same strand. The lower panels are the background distribution of these geometry terms among experimental RNA structures. Distributions for Watson–Crick (WC) and G:U wobble (g/u) base pairs are shown in light and dark gray, respectively, while the mean and standard deviation of the distributions are listed within the parentheses in the legend. The distribution of geometry terms for other atom types are shown in Supplementary Fig. S1. Here, P[i], P[i+1] and P[i-1] refer to the P atoms of nucleotide i and those of the previous and subsequent nucleotide along the sequence. |
