Individual side-chains from these helices participate either in core packing within individual domains, or in contacts across the interdomain interface.
The positioning of the different helices on the page is adjusted for artistic convenience, and is arranged so that the chain does not cross itself.
These arms are pushed into this position by a ' pedestal ' of three a helices.
These double helices are separated by single-strand sequences of zero or more residues.
Effect of a triplex-binding ligand on parallel and antiparallel triple helices using short unmodified and arcidine-linked oligonucleotides.
The existence of a pseudo-fivefold symmetry within the resulting bundle of 20 transmembrane helices also helped interpretation in terms of the amino-acid sequence.
The number of helices is expressed as a fraction of the total number of helices to make the bars comparable between different organisms.
Different conductance levels correspond to different numbers of helices in the bundle.
