Definitions

  • the present invention relates to the use of certain laccases as color transfer-inhibiting active ingredients in the washing of textiles as well as detergents containing these laccases.
  • Laccases (EC 1.10.3.2) are copper-containing, "blue" enzymes that are found in many plants, fungi and microorganisms, and laccases are oxidoreductases.
  • the catalytically active center contains four copper ions, which can be distinguished by their spectroscopic properties.
  • blue type 1 copper is involved in substrate oxidation
  • a type 2 and two type 3 copper ions form a trinuclear cluster that binds oxygen and reduces it to water.
  • Laccases are also referred to as p-diphenol oxidases.
  • laccases oxidize many other substrates such as methoxy-substituted phenols and diamines. With respect to their substrates, laccases are surprisingly unspecific.
  • laccases Because of their broad substrate specificity and their ability to oxidize phenolic compounds, laccases have aroused great interest in industrial applications. Promising areas for the use of laccases include, for example, the delignification and gluing of wood fiber boards, the dyeing of fabrics and the detoxification of dye waste water in the textile industry, as well as the use in biosensors.
  • laccases can also oxidize substrates that would otherwise be unable to oxidize.
  • the mediators are typically "small molecule compounds" which are oxidized by laccases. The oxidized mediator then oxidizes the actual substrate.
  • the first laccase was found as early as 1883 in the Japanese lacquer tree (Rhus vernicifera). Laccases are found in many plants such as peach, tomato, mango and potato; Laccases are also known from some insects.
  • laccases are derived from fungi, such as the species Agaricus, Aspergillus, Cerrena, Curvularia, Fusarium, Lentinius, Monocillium, Myceliophtora, Neurospora, Penicillium, Phanerochaete, Phlebia, Pleurotus, Podospora, Schizophyllum, Sporotrichum, Stagospora and Trametes.
  • This Farbin horrintulsver Sung washed, ie cleaner, textiles can be based on the one hand on the fact that dye components are removed by the washing process from the textile ("fading"), on the other hand, from other colored fabrics detached dyes on the textile reflected (“discoloration").
  • the discoloration aspect may also play a role in undyed laundry items when washed together with colored laundry items.
  • detergents especially if they are provided as so-called color or colored laundry detergents for colored textiles, contain active ingredients which prevent the detachment of dyes from the textile or At least the deposition of detached, located in the wash liquor to avoid dyes on textiles.
  • liquid detergents or cleaners for example, from an aesthetic point of view, should be clear and transparent or at least translucent and should also be sold in transparent / translucent packaging.
  • the present invention is therefore based on the object to provide a suitable color transfer inhibitor, which avoids the disadvantages known from the prior art or at least reduced, and is useful in both solid and aqueous detergent formulations.
  • a first subject of the present invention is therefore a detergent containing at least one laccase as a color transfer inhibitor.
  • Laccases from fungi, plants and in particular bacteria which have a low redox potential are preferred according to the invention, the standard redox potential of laccases being defined as the potential of the T1 copper center, as described in Mot AC, Silaghi-Dumitrescu R., Laccases : complex architectures for one-electron oxidations., Biochemistry (Moses). 2012 Dec; 77 (12): 1395-407.
  • the redox potential should be less than about 460 mV in order to be classified as low according to the invention.
  • a common method for determining the redox potential is described in the publication by Xu et al. 1996: "Biochimica. A study of a series of recombinant fungal laccases and bilirubin oxidase that exhibit significant differences in redox potential, substrate speeificity and stability" and Biophysica Acta 1292, 303-31 1.
  • laccases which are the consensus sequence are particularly preferred.
  • HCHx (3) Hx (4) M where x stands for "any amino acid” and the number following the x in brackets indicates the number of arbitrary amino acids.
  • Very particularly preferred laccases according to the invention are those which comprise an amino acid sequence which corresponds to the amino acid sequence shown in SEQ ID NO. 1 or SEQ ID NO. 2 at least 70% and more preferably at least 75%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90% of the total amino acid sequence. , 90.5%, 91%, 91, 5%, 92%, 92.5%, 93%, 93.5%, 94%, 94.5%, 95%, 95.5%, 96%, 96 , 5%, 97%, 97.5%, 98%, 98.5% and 99% is identical.
  • SEQ ID NO. 1 is the sequence of a B. licheniformis laccase comprising 513 amino acids.
  • SEQ ID NO. Figure 2 is the sequence of a Streptomyces sviceus laccase comprising 325 amino acids.
  • sequence comparison is based on the BLAST algorithm established and commonly used in the prior art (see, for example, Altschul, SF, Gish, W., Miller, W., Myers, EW & Lipman, DJ. (1990) "Basic local alignment search tool.” 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.3389-3402) and in principle occurs by assigning similar sequences of nucleotides or amino acids in the nucleic acid or amino acid sequences to one another. A tabular assignment of the respective positions is referred to as alignment.
  • Another algorithm available in the prior art is the FASTA algorithm. Sequence comparisons (alignments), in particular multiple sequence comparisons, are created with computer programs.
  • Such a comparison also allows a statement about the similarity of the compared sequences to each other. It is usually given in percent identity, that is, the proportion of identical nucleotides or amino acid residues at the same or in an alignment corresponding positions.
  • the broader concept of homology involves conserved amino acid substitutions in the consideration of amino acid sequences, that is, amino acids with similar chemical activity, as these usually perform similar chemical activities within the protein. Therefore, the similarity of the sequences compared may also be stated as percent homology or percent similarity.
  • Identity and / or homology information can be made about whole polypeptides or genes or only over individual regions. 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.
  • nucleic acid or amino acid sequence can be small and comprise only a few nucleotides or amino acids. Often, such small regions exert essential functions for the overall activity of the protein. It may therefore be useful to relate sequence matches only to individual, possibly small areas. Unless otherwise indicated, identity or homology information in the present application, however, refers to the total length of the particular nucleic acid or amino acid sequence indicated.
  • laccases which can be used in the detergent according to the invention are obtainable from plants, fungi and preferably from bacteria, in particular from Bacilli and Actinomycetes.
  • the natural production quantities of the laccases are often very low. It may therefore be useful to increase production by expressing laccase genes in foreign production hosts.
  • vectors which contain a nucleic acid which codes for a laccase which can be used according to the invention are used for this purpose.
  • These may be DNA or RNA molecules. They can be present as a single strand, as a single strand that is complementary to this single strand, or as a double strand. Especially in the case of DNA molecules, the sequences of both complementary strands must be taken into account in all three possible reading frames. Furthermore, it should be noted that different codons, so base triplets, can code for the same amino acids, so that a particular amino acid sequence can be encoded by several different nucleic acids. The person skilled in the art is able to determine these nucleic acid sequences beyond doubt since, despite the degeneracy of the genetic code, individual codons can be assigned defined amino acids.
  • nucleic acids coding for this amino acid sequence on the basis of an amino acid sequence.
  • one or more codons may be replaced by synonymous codons.
  • This aspect relates in particular to the heterologous expression of the enzymes which can be used according to the invention.
  • every organism for example a host cell of a production strain, has a certain codon usage. Codon usage is understood to mean the translation of the genetic code into amino acids by the particular organism. Bottlenecks in protein biosynthesis can occur if the codons lying on the nucleic acid in the organism face a comparatively small number of loaded tRNA molecules.
  • a person skilled in the art can use well-known methods such as chemical synthesis or the polymerase chain reaction (PCR) in combination with molecular biological and / or proteinchemical standard methods, using known DNA and / or amino acid sequences, the corresponding nucleic acids to complete genes manufacture.
  • PCR polymerase chain reaction
  • Such methods are for example from Sambrook, J., Fritsch, E.F. and Maniatis, T. 2001. Molecular cloning: a laboratory manual, 3rd Edition Cold Spring Laboratory Press.
  • vectors are understood as consisting of nucleic acids which, as a characteristic nucleic acid region, are one for a method according to the invention contain insertable laccase encoding nucleic acid. They are able to establish them as a stable genetic element in a species or cell line over several generations or cell divisions.
  • Vectors, especially when used in bacteria, are special plasmids, ie circular genetic elements.
  • a nucleic acid encoding a laccase which can be used according to the invention is cloned into a vector.
  • the vectors include, for example, those whose origin are bacterial plasmids, viruses or bac teriophages, or predominantly synthetic vectors or plasmids with elements of various origins. With the other genetic elements present in each case, vectors are able to establish themselves as stable units in the relevant host cells over several generations. They may be extrachromosomal as separate units or integrated into a chromosome or chromosomal DNA.
  • Expression vectors comprise nucleic acid sequences which enable them to replicate in the host cells containing them, preferably microorganisms, particularly preferably bacteria, and to express a contained nucleic acid there.
  • expression is influenced by the promoter (s) that regulate transcription.
  • the expression may be effected by the natural promoter originally located in front of the nucleic acid to be expressed, but also by a promoter of the host cell provided on the expression vector or also by a modified or completely different promoter of another organism or another host cell.

  • all cells ie prokaryotic or eukaryotic cells
  • host cells are suitable as host cells.
  • preferred host cells are characterized by good microbiological and biotechnological handling. This concerns, for example, easy culturing, high growth rates, low demands on fermentation media and good production and secretion rates for foreign proteins.
  • Preferred host cells according to the invention secrete the (transgenially) expressed protein into the medium surrounding the host cells.
  • the laccases can be modified by the cells producing them after their production, for example by attachment of sugar molecules, formylations, aminations, etc. Such post-translational modifications can functionally affect the laccases.
  • genetic regulatory elements which are provided, for example, on the vector but which can also be present in these cells from the outset.

  • Preferred host cells are prokaryotic or bacterial cells. Bacteria are characterized by short generation times and low demands on cultivation conditions. As a result, inexpensive cultivation methods or production methods can be established. In addition, the expert has a wealth of experience in bacteria in fermentation technology. For a specific production, gram-negative or gram-positive bacteria may be suitable for a wide variety of reasons to be determined experimentally in individual cases, such as nutrient sources, product formation rate, time requirement, etc.

  • Gram-negative bacteria can also be designed such that they eject the expressed proteins not only into the periplasmic space but into the medium surrounding the bacterium.
  • gram-positive bacteria such as Bacilli or Actinomycetes or other representatives of Actinomycetales have no outer membrane, so that secreted proteins are released immediately into the medium surrounding the bacteria, usually the nutrient medium, from which the expressed proteins can be purified. You can take off the medium directly isolated or further processed.
  • Gram-positive bacteria are related or identical to most of the organisms of origin for technically important enzymes and usually form even comparable enzymes, so they have a similar codon use and their protein synthesizer is naturally aligned accordingly.

  • the host cell may also be a eukaryotic cell, which is characterized in that it has a cell nucleus.
  • eukaryotic cells are capable of post-translationally modifying the protein formed. Examples thereof are fungi such as Actinomycetes or yeasts such as Saccharomyces or Kluyveromyces. This may be particularly advantageous, for example, if the proteins are to undergo specific modifications in the context of their synthesis that enable such systems. Modifications that eukaryotic systems perform, especially in connection with protein synthesis, include, for example, the binding of low molecular weight compounds such as membrane anchors or oligosaccharides.
  • Such oligosaccharide modifications may be desirable, for example, for lowering the allergenicity of an expressed protein. Coexpression with the enzymes naturally formed by such cells, such as cellulases or lipases, may also be advantageous. Furthermore, for example, thermophilic fungal expression systems may be particularly suitable for the expression of temperature-resistant proteins or variants.
  • the said host cells are cultivated and fermented in the usual way, for example in discontinuous or continuous systems. In the first case, a suitable nutrient medium is inoculated with the host cells and the product is harvested from the medium after an experimentally determined period of time.
