Fluorinated hydrophobin and uses thereof

Modified protein comprising a molecule of hydrophobin and at least one fluorocarbon group bound covalently to an amino acid of hydrophobin, obtainable by reaction of a hydrophobin with a fluorinated compound of formula: Y-RH-RF, in which Y is a functional group capable of reacting with an amino acid residue of the hydrophobin forming a covalent bond between the fluorinated compound and said amino acid of the hydrophobin, RH is an optional hydrocarbon group, non-fluorinated, aliphatic and/or aromatic, optionally including heteroatoms, and RF is a fluorinated or perfluorinated hydrocarbon residue, linear, branched or cyclic, optionally including one or more heteroatoms.
