A large number of Z-DNA hexamer duplex structures and a few oligomers of different lengths are available, but here the first crystal structure of the d(CGCGCGCGCGCG)2 dodecameric duplex is presented. Two synchrotron data sets were collected; one was used to solve the structure by the single-wavelength anomalous dispersion (SAD) approach based on the anomalous signal of P atoms, the other set, extending to an ultrahigh resolution of 0.75 Å, served to refine the atomic model to an R factor of 12.2 ...[more]
