The two HC, a-helical domains are helically interwound, giving the molecules a long, rigid superhelical structure with 2 globular headpieces. |

The two monomers are interwound, forming a lobster-like structure with two flexible arms consisting of two antiparallel-ribbons. |

It was found that an interwound configuration describes the data well, provided interactions among supercoils are accounted for in the second virial approximation. |
