Does a synthetic peptide containing the leucine-zipper domain of c-myb form an alpha-helical structure in solution?
We have examined a synthetic peptide containing the putative leucine zipper domain of the chicken c-myb proto-oncogene using circular dichroism (CD) spectroscopy. The peptide adopts an alpha-helical structure only at low temperatures and in the presence 2,2,2-trifluoroethanol.
