Popis: Two amino acid sequences from potentially helical fragments of low-sulphur proteins from α-keratin have been analysed computationally and periods 9.4 and 28 residues long noted in the axial disposition of charged residues. Ionic interactions between chains have also been calculated and these indicate a preference for the helical fragments to aggregate in parallel with zero shift between chains in a manner essentially identical to that found for α-tropomyosin.
