  • (7) The melting profile exhibited two transitions--one at about 35 degrees C and one above 50 degrees C. Our spectral data showed that helices I and II were stable during the first transition, and agreed with other data that helix III was the most likely helix to have melted.

  • (10) In these discoidal complexes, the alpha-helical content was estimated to be 65%, with the rest of the structure being essentially unordered.
  • (11) A modified plot accounting for amphiphilic helices indicates 5-6 such alpha-segments.

  • (14) These results are consistent with a structural model for the membrane in which the peptide chains vary greatly in the proportion of helical segments and polar regions which they contain.
  • (15) The latter, which is external and solvent accessible, is associated with a distortion in the alpha-helix centered around Tyr33 which consists of a significant increase in the CO(i-4)-N(i) and CO(i-4)-NH(i) distances relative to those in the rest of the helix, as well as a significant departure in the phi, psi angles of Tyr33 relative to regular helical geometry.
  • (16) Eight alpha-helices behave as relatively rigid bodies and corner regions are more flexible, showing larger fluctuations.
