Definitions

  • Ice formation on surfaces can lead to significant safety problems, and in extreme cases, an icy plane or motor vehicle can no longer be operated.
  • the formation of ice on surfaces can also lead to undesirable changes in the properties of the corresponding components.
  • the aerodynamic properties of the wind turbine can change as a result of ice formation.
  • Various techniques are known for removing ice layers or preventing ice formation on surfaces.
  • X, C and the indices standing at X and C have the above meaning
  • the indices n and m are numbers between 0 and 350, preferably 15 to 300
  • the proteins further by the above-mentioned Distinguish contact angle change and it is still at least 6 of the radicals named C is cysteine. Most preferably, all of the C radicals are cysteine.
  • the fusion hydrophobin has in addition to the fusion partner mentioned as one of the groups X n or X m or as a terminal Part of such a group on a so-called affinity domain (affinity tag / affinity tail) on.
  • affinity domains include (His) k, (Arg) k, (Asp) k, (Phe) k or (Cys) k groups, where k is generally a natural number from 1 to 10. It may preferably be a (His) k group, where k is 4 to 6.
  • Hydrophobins including their sequences are disclosed, for example, in WO 2006/82251. Unless stated otherwise, the sequences given below refer to sequences disclosed in WO 2006/82251. An overview table with the SEQ-I D numbers can be found in WO 2006/82251 on page 20.
  • Particularly suitable according to the invention are the fusion proteins yaad-Xa-dewA-his (SEQ ID NO: 20), yaad-Xa-rodA-his (SEQ ID NO: 22) or yaad-Xa-basfl-his (SEQ ID NO: 24) with the polypeptide sequences given in parentheses and the nucleic acid sequences coding therefor, in particular the sequences according to SEQ ID NO: 19, 21, 23.
  • Particularly suitable derivatives for carrying out the present invention are from yaad-Xa-dewA-his (SEQ ID NO: 20), yaad-Xa-rodA-his (SEQ ID NO: 22) or yaad-Xa-basf1-his (SEQ ID NO: 24) derivatives derived from truncation of the yaad fusion partner.
  • yaad-Xa-dewA-his SEQ ID NO: 20
  • yaad-Xa-rodA-his SEQ ID NO: 22
  • yaad-Xa-basf1-his SEQ ID NO: 24
  • the truncated residue should comprise at least 20, preferably at least 35, amino acids.
  • hydrophobins used according to the invention for modifying open-cell foams can be prepared chemically by known methods of peptide synthesis, such as, for example, by Merrifield solid-phase synthesis.
  • Examples include the surfaces of aircraft and spacecraft, automobiles, motorcycle helmets, all types of windows such as window panes, car windows, aircraft windshields, steel structures such as power line masts, power lines such as power lines of overhead power lines, industrial plants or electrical equipment.
  • a formulation which comprises at least water or aqueous solvent mixture and at least one hydrophobin.
  • the formulation preferably comprises a suitable buffer.
  • a suitable buffer depending on the pH range intended for the coating. Examples include potassium dihydrogen phosphate buffer, tris (hydroxymethyl) aminomethane buffer (Tris buffer), borax buffer, sodium bicarbonate buffer or sodium hydrogen phosphate buffer. Preferred is Tris buffer.
  • Suitable surfactants are, for example, nonionic surfactants which comprise polyalkoxy groups, in particular polyethylene oxide groups. Examples include polyoxyethylene stearates, alkoxylated phenols and the like. Further examples of suitable surfactants include polyethyleneglycol (20) sorbitan monolaurate (Tween ® 20), polyethyleneglycol (20) sorbitanmonopal- palmitate (Tween ® 40), polyethyleneglycol (20) sorbitan monostearate (Tween ® 60), polyethyleneglycol (20) sorbitan monooleate ( Tween ® 80), cyclohexyl-methyl-ß-D maltoside, cyclohexyl-ethyl-.beta.-D maltoside, cyclohexyl-n-hexyl-ß-D maltoside, n-undecyl-beta D-maltoside, n-octyl
  • Substrate glass (window glass, Süd Weg Glas, Mannheim)
