Definitions

  • the present invention is in the field of enzyme technology, in particular the anti-pilling effect of enzymes such as are used, for example, in detergents.
  • the invention relates to a detergent which contains a cutinase as defined herein.
  • the present invention also relates to a method for cleaning textiles and the use of the agent according to the invention for removing soiling. Furthermore, the invention is directed to the use of a cutinase to reduce pilling effects and anti-gray in a detergent.
  • Pilling is the name given to the formation of pebbles or fluff in fabrics. These small lint appear especially in short-fiber fabrics. With long-fiber and twisted fibers, on the other hand, pilling is less pronounced. In general, these nodules are caused by loose fibers in the fabric or those that have become detached from the fabric. Due to their smooth surface, synthetic fibers tend to pilling more than natural fibers, because synthetic fibers can be detached from the fabric more quickly than rough natural fibers. In the case of woolen fabrics, these fibers "felt” mainly through mechanical friction and form pebbles on the surface.
  • Pilling Due to the formation of pods on the surface, fabrics quickly look used and older than they are. In contrast, the functionality of the material is hardly or not at all impaired. For example, the constant thinning of the fabric even increases the breathability. Pilling takes place particularly in areas subject to high mechanical stress, usually the shoulder and waistband areas. Due to the continuous thinning of the fabric, these stressed areas in particular are at risk of forming holes or even tearing.
  • a cutinase from Thermomonospora curvata DSM 43183 shows an anti-pilling effect in the washing process.
  • pre-pilled tissue or new tissue is less pilled after 20 washes with a detergent which contains the cutinase according to the invention.
  • the object described above, on which the present application is based, is achieved in that a cutinase is added to detergents which has at least 70% sequence identity with the amino acid sequence given in SEQ ID NO: 1 over its entire length.
  • the addition of the cutinase has the effect that textiles washed with the agents according to the invention, in particular polyester textiles, have a significantly reduced pilling compared to a control detergent without cutinase.
  • the present invention is therefore directed to a detergent, characterized in that it contains a cutinase, the cutinase being a cutinase which has at least 70% sequence identity with the amino acid sequence given in SEQ ID NO: 1 over its entire length.
  • the present invention is directed to processes for cleaning textiles, characterized in that an agent according to the invention is used in at least one process step.
  • the present invention is also directed to the use of a detergent as described herein, particularly preferably liquid detergent, for removing soiling.
  • another aspect of the invention includes the use of a cutinase for reducing pilling effects of a detergent, particularly preferably a liquid detergent, the agent containing the cutinase, the cutinase being a cutinase which has at least 70% sequence identity with that in SEQ ID NO: 1 has indicated amino acid sequence over its entire length.
  • a cutinase (EC 3.1.1.74) or cutin hydrolase is an enzyme that belongs to the ⁇ / ⁇ hydrolases and hydrolyses cutin. Cutinase is produced, among other things, by some phytopathogenic fungi and bacteria are formed (through the cutinase the fungi are able to break down the ester bond of the cutin in the cuticula of the plants and thus penetrate the plants).
  • the cutinase is a cutinase from Thermomonospora curvata, in particular the cutinase with the amino acid sequence according to SEQ ID NO: 1, or a cutinase derived therefrom, for example by means of mutagenesis.
  • the agents according to the invention contain the cutinase in an amount of 0.00001-1% by weight, preferably in an amount of 0.0001-0.5% by weight, particularly preferably in an amount of 0.001-0.1% by weight. -% based on the active protein.

  • nucleic acid or amino acid sequences is determined by a sequence comparison.
  • This sequence comparison is based on the BLAST algorithm established and commonly used in the prior art (cf. for example Altschul, SF, Gish, W., Miller, W., Myers, EW & Lipman, DJ (1990) "Basic local alignment search tool.” J. Mol. Biol. 215: 403-410 , and Altschul, Stephan F., Thomas L. Madden, Alejandro A. Schaffer, Jinghui Zhang, Hheng Zhang, Webb Miller, and David J. Lipman (1997): "Gapped BLAST and PSI-BLAST: a new generation of protein database search programs "; Nucleic Acids Res., 25, pp.
  • Sequence comparisons are also possible with the computer program Vector NTI® Suite 10.3 (Invitrogen Corporation, 1600 Faraday Avenue, Carlsbad, California, USA) with the specified standard parameters, whose AlignX module for the sequence comparisons is based on ClustalW.
  • Such a comparison also allows a statement to be made about the similarity of the compared sequences to one another. It is usually given in percent identity, that is to say the proportion of identical nucleotides or amino acid residues in the same positions or positions corresponding to one another in an alignment.
  • the broader term of homology includes conserved amino acid exchanges in the case of amino acid sequences, i.e. amino acids with similar chemical activity, since these usually exert similar chemical activities within the protein. Therefore, the similarity of the compared sequences can also be given as percent homology or percent similarity. Identity and / or homology information can be made over entire polypeptides or genes or only over individual areas. Homologous or identical regions of different nucleic acid or amino acid sequences are therefore defined by matches in the sequences.
  • Such areas often have identical functions. They can be small and only contain a few nucleotides or amino acids. Such small areas often have essential functions for the overall activity of the protein. It can therefore be useful to relate sequence matches only to individual, possibly small areas. Unless otherwise stated, identity or homology details in the present application refer to the total length of the nucleic acid or amino acid sequence specified in each case.
  • the cutinase is characterized in that its anti-pilling performance is not significantly reduced compared to that of a cutinase which comprises an amino acid sequence which corresponds to the amino acid sequences given in SEQ ID NO: 1, ie at least 70% , 75%, 80%, 85%, 90%, 95% of the reference anti-pilling performance.

In general, a low specific activity can be compensated for by adding a larger amount of protein.
  • Proteins can be combined into groups of immunologically related proteins by reacting with an antiserum or a specific antibody. Members of such a group are distinguished by the fact that they have the same antigenic determinant recognized by an antibody. They are therefore structurally so similar to one another that they can be recognized by an antiserum or certain antibodies.
  • Another subject matter of the invention is therefore cutinases, which are characterized in that they have at least one and increasingly preferably two, three or four matching antigenic determinants with a cutinase used in an agent according to the invention.
