Abstract

Disclosed herein are a materials such as a coating, an elastomer, an adhesive, a sealant, a textile finish, a wax, and a filler for such a material, wherein the material includes an proteinaceous molecule such as a peptide and/an enzyme that confer a metal binding, an anti-fouling and/or an antibiotic property to the material. In particular, disclosed herein are marine coatings such as a marine paint that comprise an anti-fouling peptide sequence that reversibly binds a metal cation that is toxic to a fouling organism. Also disclosed herein are methods of reducing fouling on a surface by treating the surface with a metal binding peptide.

3. The marine coating composition of claim 1, wherein about 5% to about 100% of the amino acids of the metal binding sequence are electron donor amino acids.

4. The marine coating composition of claim 3, wherein at least 25% of the electron donor amino acids are one or more amino acids selected from the group consisting of a histidine, a lysine, and an arginine.

5. The marine coating composition of claim 1, wherein the proteinaceous molecule is cysteine-free.

6. The marine coating composition of claim 1, wherein each amino acid of the proteinaceous molecule is independently selected from the group consisting of the D-stereoisomer and L-stereoisomer forms of the amino acids.

7. The marine coating of composition of claim 1, wherein the marine coating possesses an enhanced metal binding activity.

8. The marine coating composition of claim 7, wherein the metal binding activity is reversible.

9. The marine coating composition of claim 1, wherein the marine coating comprises an immobilization agent, and wherein the proteinaceous molecule is immobilized to the immobilization agent.

10. The marine coating composition of claim 9, wherein the immobilization of the proteinaceous molecule by the immobilization agent is reversible so that the proteinaceous molecule may be released from the immobilization agent, and wherein upon release of the proteinaceous molecule the immobilization agent may immobilize another like or different proteinaceous molecule.

11. The marine coating composition of claim 1, wherein the marine coating comprises at least one anti-biological agent selected from the group consisting of a peptidic agent of SEQ ID Nos 1-203, a peptidic agent having functionally equivalent amino acid substituted sequences having no more than a +/−
