Four highly pseudosymmetric and/or twinned structures of d(CGCGCG)2 extend the repertoire of crystal structures of Z-DNA.

Abstract

DNA oligomer duplexes containing alternating cytosines and guanines in their sequences tend to form left-handed helices of the Z-DNA type, with the sugar and phosphate backbone in a zigzag conformation and a helical repeat of two successive nucleotides. Z-DNA duplexes usually crystallize as hexagonally arranged parallel helical tubes, with various relative… (More)
