Coiled-coil This is a heterodimeric coiled-coil. The helices are slightly kinked, so that they can grip the DNA at one end. The alpha-helix is right-handed, but its coiled-coils are usually left-handed. Looking at the end away from the DNA, the coiled-coil appears only slightly twisted. Type "rama" in the box to see how close all amino acids are to the expected torsion angles. Crystal structure of the heterodimeric bZIP transcription factor c-Fos-c-Jun bound to DNA.
