Extended Data Fig. 2: Similarities among the atomic models of the SX and ED structures.

(a–c) Relation plots between the SX and ED structures in 1,2- (a) and 1,3- (b) bond distances for the same pair of non-hydrogen atoms and in B-factors (c) for the same non-hydrogen atoms. A linear regression is drawn for the rt-ED in (c). See also Supplementary Table 1 for bond lengths between non-hydrogen atoms. Correlation coefficients between the SX and ED data are also shown in the graphs.
