In discussions of amino acid positioning and function along an alpha
helix, a helical wheel diagram is sometimes desirable. Unfortunately, I
and my collegues have not been able to find a simple Mac program that
creates and positions an amino acid sequence along a helical wheel. If
anyone has or knows of Mac freeware or shareware that can create these
schematic diagrams, please let me know at nveldhoe at sol.uvic.ca. Thanks.
