The shape of a membrane protein derived from rotational diffusion.

F Jähnig

    European Biophysics Journal : EBJ
    |January 1, 1986
    PubMed
    Summary

    This study models membrane proteins as cylinders with elliptical cross-sections. The rotational diffusion coefficient was calculated based on the axial ratio of these cross-sections.
