Definition of superhelix in English:

superhelix

nounPlural superhelices ˈsuːpəhiːlɪksˈso͞opərˌhēliks

Biochemistry

A helical structure formed from a number of protein or nucleic acid chains which are individually helical.
〔生化〕超螺旋
Example sentencesExamples
- The double helix of DNA winds about individual nucleosomes, forming a superhelix.
- Apart from its effect on the molecular free energy, the topological constraint determines the total length and diameter of the superhelix, and hence, the volume excluded to another supercoil.
- Consequently, they proposed a compact structural motif for the entire peptide in which the [beta] sheet structure of the superhelix is a sheet with three strands connected by two turns.
- Of course, this behavior can be attributed to deficiencies in the theory, but a more obvious explanation can be found in branching of the superhelix.
- The crystal structure reveals a novel supercoil structure in which four parallel WAT chains form a left-handed superhelix around an antiparallel left-handed proline rich attachment domain helix resembling polyproline II.

Derivatives

superhelical

adjective ˌsuːpəˈhɛlɪk(ə)l

Biochemistry

Relating to or of the nature of a superhelix.
changes in the superhelical density of the DNA
Example sentencesExamples
- a rigid, superhelical filament
- Intriguingly, experiments show clear differences in the dependence of the formation of paired hix sites and of the formation of the invertasome on the superhelical density [sigma] of the DNA substrate.
- Based on our previous work on superhelical DNA and polynucleosomes, it reintegrates aspects of the ‘solenoid’ and the ‘zig-zag’ models.
- Its major biological role in the bacterial cell is the removal of excessive negative supercoils from DNA to maintain the DNA at optimal superhelical density along with DNA gyrase.
