Figure 4
Resolution dependence of peak frequencies in m|Fo| − D|Fc| maps. The m|Fo| − D|Fc| maps were drawn at the resolution of the upper limit of each bin. ALL (P), A-DNA (P), B-DNA (P) and Z-DNA (P) denote the peak frequencies of P atoms in all DNA forms, in A-DNA, in B-DNA and in Z-DNA, respectively. ALL (C5/C2) is the peak frequency of C5 of purine or C2 of pyrimidine in all DNA forms. The peak frequencies in m|Fo| − D|Fc| maps obtained by simulations using FoFc error or sigmaF error are also shown by a dotted line with cross marks and a dashed line with plus marks, respectively. The bar indicates the standard deviation within all residues. Atoms without alternative locations were used to draw figures. |
