    Nuclear Magnetic Studies of Alamethicin by Martin, D

    Published 1974
    “…</p> <p>This finding that alamethicin F30 is not cyclic but is a linear peptide with the C- and N- termini blocked by groups which are undetected by conventional procedures is not in fact in disagreement with any of the previous sequence/composition studies of alamethicin. This finding is obviously of importance in trying to understand the interesting conduction properties shown by alamethicin.…”
