Abstract

A polypeptide is provided that has a secondary structure characterized by at least three beta-sheet/beta-turn structures, and that is not a naturally occurring fibrous protein. Such polypeptides, illustrated by one modeled on elastin, are useful in prosthesis.

Claims

-34-AMENDED CLAIMS[received by the International Bureau on 14 May 1998 (14.05.98); original claims 1-26 replaced by amended claims 1-25; new claims 26 and 27 added (4 pages)]
1. A polypeptide that comprises at least three beta-sheet/beta-turn structures and at least one amino acid residue capable of participating in cross-linking, and that is not a naturally occurring fibrous protein.
2. The polypeptide of claim 1, wherein each of the beta-sheet structures comprises from 3 to about 7 amino acid residues.
3. The polypeptide of claim 2, wherein each of the beta-sheet structures comprises from about 5 to about 7 amino acid residues.
4. The polypeptide of claim 1, wherein the polypeptide consists essentially of a portion of the amino acid sequence set forth in Figure IB.
5. The polypeptide of claim 4, wherein the polypeptide comprises an amino acid sequence selected from the group consisting of amino acid residues 374-499, 19-160, 188-367 and 607-717, respectively, of Figure IB.
