摘要：
Described is a method of fabricating biologically active, unnatural polypeptides. The method includes the steps of selecting a biologically active polypeptide or biologically active fragment thereof having an amino acid sequence comprising α-amino acid residues, and fabricating a synthetic polypeptide that has an amino acid sequence that corresponds to the sequence of the biologically active polypeptide, but wherein about 14% to about 50% of the α-amino acid residues found in the biologically active polypeptide or fragment of step (a) are replaced with β-amino acid residues, and the α-amino acid residues are distributed in a repeating pattern.
