Figure 6 Stereoview (Kraulis, 1991[Kraulis, P. J. (1991). J. Appl. Cryst. 24, 946-950.]; Merritt & Bacon, 1997[Merritt, E. A. & Bacon, D. J. (1997). Methods Enzymol. 277, 505-524.]) of the form IVa and form IVb pseudo-hexadecamers resulting from the superpositioning of the C^ atoms of the protein molecules of their structures. Note the near-exact match of the 3'-OH ribose rings and the lack of matches elsewhere. The form IVb DNA is shown in red and the form IVa DNA is shown in white, retaining its A7 base in the anti conformation.
