Examples of helix

helix
Effect of a triplex-binding ligand on parallel and antiparallel triple helices using short unmodified and arcidine-linked oligonucleotides.
The component helices might be held together only by the continuity of the strands, or they might undergo pairwise coaxial stacking.
The outer surface is formed by a -hairpin and two helices.
The catalytic subunit has an overall -helical structure containing five helices.
At # low salt concentration the junction is extended, with no stacking of helices.
As with the other structures, the junction is a right-handed antiparallel cross of pairwise, coaxially stacked helices.
The dynamic programming methods predict a larger proportion of long range helices than actually occur.
Isolated base pairs are usually unstable ; hence, helices usually consist of at least two pairs.
In this model, the amphipathic peptide helices associate to form a bundle, which resembles a barrel composed of helices as staves.
Sensor domains were identified as the segment between predicted transmembrane helices associated with histidine kinase domains.
Thus, fusion between double helices can occur between strands of the same polarity or of opposite polarity.
The inner wall of the complex is formed by the 9 a-apoprotein helices.
The peptides are 20 and 23 residues long respectively and are predicted to form amphipathic helices.
In the latter cases, the coupling efficiency will depend on the nature of the interactions between helices.
A mean of 81 % of the welldetermined helices are present in the comparative structure.
