title: A two-dimensional representation of relative orientations of alpha-helix residues.
abstract: Simple rules for constructing a two-dimensional representation of relative orientations of alpha-helix residues are presented. The repeat units in tropomyosin and haemagglutinin, together with their interrelationships, are also illustrated.
