![]() ![]() In addition, the effects, or postulated effects, of the alpha-helix dipole on the following phenomena are briefly reviewed: (i) the packing of alpha-helices in proteins (ii) electron, proton and ion conduction along the helix axis (iii) ion transport along multiple helix channels in membranes (iv) flow of electrons guided by helix dipole fields in photosynthetic reaction centres (v) voltage-dependent pore-formation in lipid membranes (vi) packing of helical peptides in water-free crystals (vii) stabilisation and destabilisation of oligopoptides by the interaction between charged side chains and the helix dipole and (viii) a pK shift of a histidine caused by the helix dipole field. In about 9 enzymes the active site is situated close to the N-terminus of a helix, in such a manner that the electrical field of the dipole may increase reaction rates.

Influenced by great engineers and innovators from the past, Helix is the long-awaited evolution of the 3-wheeled, tilting vehicle. Find out what works well at Helix Electric from the people who know best. The alpha-helix carries a considerable dipole moment, the effect of which can be approximated by placing 0.5-0.7 positive unit charge near the N-terminus and 0.5-0.7 negative unit charge near the C-terminus of the helix.
