A superhelix is a molecular structure in which a helix is itself coiled into a helix. This is significant to both proteins and genetic material, such as overwound circular DNA. The earliest significant reference in molecular biology is from 1971, by F. B. Fuller:

超螺旋（英文：Superhelix）是一種本身就是螺旋狀的物質再次以螺旋狀纏繞成的一種特殊型態的分子結構。 這種結構對於 蛋白質 和 遺傳物質 都非常重要。

The superhelix consists of three smaller left-handed helices whose structure provides high tensile strength through their rigidity and relative inelasticity [3]. The basic peptide sequence of these smaller helices consists of glycine–X–Y repeats, where X and Y are proline and hydroxyproline (HP), respectively, in 10% of these repeats [26] .

To model the nucleosome superhelix, a right-handed helix, and a left-handed superhelix as a TH requires Tw > 0 and τ < 0, so that Tw < Tw o. The ideal superhelix model in Richmond and Davey has κ ≈ 4.5°/bp, Ri ≈ 3.4 Å/bp, radius ≈42 Å, and pitch ≈26 Å, corresponding to a torsion of τ ≈ −0.45°/bp in the TH.

2008年8月1日 · Here we focus attention only on the geometry of the superhelix and present two distinct mathematical expressions that rely on the DNA helical parameters (Shift, Slide, Rise, Tilt, Roll, Twist). One representation requires torsion for superhelix formation; the other requires shear.

A superhelix is a molecular structure in which a helix is itself coiled into a helix. This is significant to both proteins and genetic material, such as overwound circular DNA. The earliest significant reference in molecular biology is from 1971, by F.B. Fuller: A geometric invariant of a space curve, the writhing number, is defined and studied.

A superhelix is a twisted structure formed by the coiling of α-helical structures, which can be stabilized by hydrophobic interactions of non-polar side-chains. It can also refer to a specific type of superhelix involved in virus-cell membrane fusion, which can be blocked through the optimization of HA stalk constructs.

2015年3月1日 · Systematic variation of the helix length revealed upper and lower size limits for successful structure determination. A beautiful but unanticipated structure was obtained that forms superhelices with left-handed twist throughout the crystal, stabilized by ligand interactions.

A C-terminal domain is identified in their crystal structure with a four-helix-bundle fold. In the topological model, the genomic dsDNA superhelix wraps around P132 basic core, and the P140 basic N-terminus binds genomic DNA, while its lipophilic C-terminal domain is embedded in the lipidic outer shell (Figure 6).

Let's demonstrate how the concept of writhing (or superhelix formation) prevents the changes in DNA twist from causing alterations in the structure of the double helix. If circular DNA is confined to a planar arrangement, the changes in linking # ∆L k = ∆T w + ∆W r can only be compensated for by equivalent changes in twist, because
