| 摘要 |
Stable, helical, biologically active peptides, particularly stable, helical, biologically active C-peptides, which comprise all or a portion of an unstructured peptide (a peptide which is unstructured in solution) linked to a scaffold (or support) polypeptide. Such peptides are referred to herein as structured C-peptides. In particular embodiments, structured C-peptides of the present invention comprise all or a portion of a binding epitope of a C-peptide, such as all or a portion of a binding epitope of a peptide derived from the carboxy-terminal region of the HIV-1 gp41 envelope glycoprotein. The C-peptide can be, for example, C34 peptide of HIV-1 gp41.
