Coiled coil design right-handed coils

The coiling together of textile staple fibres, yams or threads to give the structure the required degree of strength, extensibility, flex resistance, etc. Twist is designated as so many turns per inch and either right hand (Z) or left hand (S). See S-Twist and Z-Twist. 

Harbury et al. (1998) described a series of peptides designed to form dimeric, trimeric, and tetrameric helical bundles with right-handed supercoils. To achieve right-handed coiled coils, rather than canonical left-handed structures, an HP pattern based on an 11-residue abcdefghij repeat was used as a template. Combinations of the hydrophobic residues Ala, lie, Leu, Val, allo-Ile, and nor-Val were considered for the a, d, and h sites. The...
