Protein Science Feb 8 (2) 370-380. PubMed Abstract A protein alpha-helix is defined by 3.6 amino acids per turn. Cyclization of the tripeptide Alanine-Leucine-Glutamate through a side chain to the N-terminus lactam bond produces cyclo-(1,3)-[ALE]-NH(2) which displays a circular dichroism spectrum typical of an alpha-helix backbone. However, proton NMR spectra show a novel cyclic peptide featuring two non-hydrogen-bonded antiparallel beta of the CD spectrum of an unordered chain, and indicate that three conformational states (a-helix, extended helix, and unordered) should be incorporated in our thinking about conformational transitions in polypeptides.
