Recent analyses have indicated that traditional refinement does not always give us accurate crystallographic heterogeneity and some information of DNA flexibility is possibly overlooked in previous crystallographic studies. We re-calculated m|Fo|-D|Fc| electron density maps of double helical DNA crystal structures in PDB to utilize the overlooked information. We observed potential conformational transitions in 27% of DNA phosphates analyzed. The present results indicate that peaks around phosphates in the m|Fo|-D|Fc| maps of Z-DNA and B-DNA sometimes corresponds to ZI ZII and A/B -> BI transitions, respectively. We also discuss effect of metal-coordination on conformational transitions in Z-DNA., 第54回日本生物物理学会年会に参加。}, title = {DNA conformational transition inferred from re-evaluation of m|Fo|-D|Fc| electron density maps}, year = {2016} }
