Conformations of C-DNA in agreement with fiber X-ray and infrared dichroism.
Different left handed double helices are proposed as models for DNA fibers in the C form. These conformations have geometrical parameters which agree well with fiber X-ray data and the orientations of their phosphate groups are in good agreement with infrared dichroism results. A complete set of atomic coordinates and dihedral angles are given together with curves of calculated diffracted intensities. The present results are compared with experimental values and with the other C-DNA models.
