Abstract
Highly repetitive proteins which are relatively insoluble in water are chemically modified to increase solubility. The protein is reacted with a functionalizing agent to introduce additional polar functionalities and disrupt the order of the protein. The solubility of the protein in water is increased by the chemical modification, while adhesive and surfactant properties are retained.
