Abstract

Isolated polypeptides are disclosed comprising an amino acid sequence encoding a monomer of a fibrous polypeptide attached to a heterologous polysaccharide binding domain. Composites comprising same, methods of generating same and uses thereof are all disclosed.

Claims (14)

1. A composite comprising resilin and a polysaccharide selected from the group consisting of cellulose, starch, dextran, glucan, chitosan, alginate and hyaluronic acid.

2. A composite comprising a fibrous polypeptide and a polysaccharide, said fibrous polypeptide comprising a heterologous polysaccharide binding domain, the composite being non-immobilized.

3. The composite of claim 1 , wherein said resilin comprises a polysaccharide binding domain.

4. The composite of claim 3 , wherein said polysaccharide binding domain is a heterologous polysaccharide binding domain.

5. The composite of claim 3 , wherein said polysaccharide binding domain is selected from the group consisting of a cellulose binding domain, a chitosan binding domain, an alginate binding domain, a starch binding domain, a dextran binding domain, a glucan binding domain and an hyaluronic acid binding domain.

6. The composite of claim 2 , wherein said fibrous polypeptide is selected from the group consisting of mussel byssus protein, resilin, silkworm silk protein, spider silk protein, collagen, elastin and fragments thereof.

7. The composite of claim 1 , further comprising an additional fibrous polypeptide being selected from the group consisting of mussel byssus protein, silkworm silk protein, spider silk protein, collagen, elastin and fragments thereof.

8. The composite of claim 1 being crosslinked.

9. The composite of claim 1 being non-crosslinked.

10. A composite comprising at least two non-identical fibrous polypeptides, wherein a first fibrous polypeptide of said at least two non-identical fibrous polypeptides comprises an amino acid sequence encoding a resilin polypeptide attached to a heterologous polysaccharide binding domain.

11. A scaffold comprising the composite of claim 1 .

12. A pharmaceutical composition comprising the composite of claim 1 .

13. A cosmetic composition comprising the composite of claim 1 .

14. A composite comprising resilin and cellulose.
