Some of the consensus structural features identified for the class of peptides using the proposed methodology. Note that in the two consensus fragments that are not contained in other consensus fragments, the basic peptide backbone is conserved, even for proline, a highly exotic amino acid, since 'N' in SMARTS does not necessarily mean an NH3 in practice.
