Abstract

The present invention relates to a bioadhesive derived from mussel. In particular, it relates to a novel Mytilus galloprovincialis foot protein type 5 (MGFP-5) and a recombinant protein that is a hybrid of MGFP-5 and foot protein type 1 (FP-1), where an adhesive protein with adhesive activity can be economically mass-produced to be used in place of chemical adhesives through the present invention.

Claims (13)

1. An adhesive protein comprising SEQ ID NO: 6.

2. The adhesive protein of claim 1 , wherein the adhesive protein further comprises a peptide of SEQ ID NO: 25 tandemly repeated 1 to 10 times.

3. The adhesive protein of claim 2 , wherein the adhesive protein comprises an amino acid selected from the group consisting of SEQ ID NO: 10, SEQ ID NO: 12, and SEQ ID NO: 14.

4. The adhesive protein of claim 1 , wherein the adhesive protein further comprises a peptide which comprises 6 histidine tags.

5. The adhesive protein of claim 4 , wherein the adhesive protein comprises an amino acid sequence selected from the group consisting of SEQ ID NO: 16, SEQ ID NO: 18, SEQ ID NO: 20, and SEQ ID NO: 22.

6. An adhesive comprising an adhesive protein according to claim 3 as an active component.

7. The adhesive of claim 6 , wherein 5% to 100% of the total number of tyrosine residues in the adhesive protein is modified to 3,4-dihydroxyphenyl-L-alanine (DOPA).

8. The adhesive of claim 6 , wherein the adhesive adheres to a substrate selected from the group consisting of plastic, glass, metal, eukaryotic cells, prokaryotic cells, and plant cell walls and lipids.

9. The adhesive of claim 6 , wherein the adhesive is applied to biological sample.

10. The adhesive of claim 6 , wherein the adhesive further comprises one or more material selected from the group consisting of surfactant, oxidant, and filler.

11. The adhesive of claim 10 , wherein the filler is selected from the group consisting of collagen, hyaluronic acid, condroitan sulfate, elastine, laminin, caseine, hydroxyapatite, and albumin, fibronectin, and hybrin.

12. The adhesive of claim 6 , wherein the adhesive is applied to substrates used in an underwater environment.

13. A coating agent containing an adhesive protein according to claim 3 as an active component.
