title: Stereochemical considerations for constructing alpha-helical protein bundles with particular application to membrane proteins.
abstract: The stereochemical constraints originally used to construct two- and three-stranded alpha-helical coiled-coils were generalized for aggregates of alpha-helices containing from 4 to 14 alpha-helices in tubular bundles. Certain features of bacteriorhodopsin show excellent correlations with these stereochemical constraints.
