Description

 Polyesterase II

The present invention is in the field of enzyme technology, in particular the anti-pilling effect of enzymes, such as those used in detergents or cleaning agents. The invention relates to a polyesterase as defined herein and an agent, in particular washing or cleaning agent, which contains this polyesterase. Furthermore, the present invention relates to a method for cleaning textiles and the use of

Agent for removing dirt according to the invention. Furthermore, the invention is directed to the use of a polyesterase for reducing pilling effects and anti-gray in an agent, preferably a washing or cleaning agent.

If washed several times, all types of textiles will pill over time. Pilling is the term for the formation of nodules or lint in fabrics. These small lint are particularly common with short-fiber fabrics. With long-fiber and twisted fibers, however, there is less pilling. In general, these nodules are caused by loose fibers in the fabric or those that have come loose from the fabric. Due to their smooth surface, synthetic fibers tend to pilling more than natural fibers, because synthetic fibers can be released from the fabric faster than rough natural fibers. In the case of woolen fabrics, these fibers “matt” mainly through mechanical friction and form nodules on the surface.

The main effect of pilling is an optical impairment. Due to the formation of nodules on the surface, fabrics quickly look used and older than they are. In addition, colored textiles appear less luminous. In contrast, the functionality of the fabric is hardly or not at all impaired. Pilling takes place in particular at places that are subject to high mechanical stress, usually in the shoulder and waist region. Due to the continuous thinning of the material, these stressed areas are particularly at risk of forming holes or even tearing. The unwanted pilling has the consequence that the textiles are impaired accordingly

Consumers are sorted out and thrown away faster than would be necessary based on the functionality of the textile.

Furthermore, textiles tend to turn gray when washed. The reason for this is that both dirt and detached pigments are released from colored clothing during the washing process. Although attempts are being made to this through various detergent ingredients in the

Keeping the washing liquor can often not prevent the dirt / pigments from being deposited on the clothing and remaining there. This is the so-called graying effect. This is particularly pronounced with some synthetic fibers such as polyamide, but also polyester. A technical solution to reduce the pilling effect has so far only been available for cotton textiles. Cellulases are used in the cleaning agent to reduce the pilling effect (DE 69632910 T3). This means that cellulases are used in the detergent to show anti-pilling or anti-gray effects and thus ensure that clothes look like new for longer. Cellulases only work on cotton textiles. For other textiles, such as

Polyester textiles, there is no comparable way to reduce pilling. Therefore, it is desirable and there is a demand for solutions that reduce the pilling of textiles, particularly textiles containing synthetic fibers such as polyester, to keep clothes looking new for as long as possible, i.e. the colors should remain strong, the shape should be preserved and the surfaces should remain smooth and undamaged.

Surprisingly, the inventors of the present invention found that the polyesterase described here, which is a hybrid of an LCC cutinase (Sulaiman et al. (2012) “Isolation of a Novel Cutinase Homolog with Polyethylene Terephthalate-Degrading Activity from Leaf- Branch Compost by Using a Metagenomic Approach ”, Appl. Environ. Microbiol. 78 (5): 1556-1562) and a polyesterase from Thermobifida fusca cutinase from Yoshida et al. WP_011291330, is active under washing process conditions and has various nourishing properties for PET textiles. This is surprising insofar as previously known cutinases and PET esterases are more active at higher temperatures (> = 60 ° C), and moreover are only able to degrade PET very slowly. However, the polyesterase used here shows rapid PET degradation at 40 ° C. It was found that the enzyme on the one hand prevents pilling on new polyester textiles or supports this effect in combination with a cellulase on polyester / cotton blended textiles. On the other hand, pills that have already been formed can be reduced, i.e. it can cause a so-called "renew" effect. The polyesterase also prevents the graying of white laundry and the fading / graying of colored laundry. It has also been found that, with appropriate dosing, all of these positive washing properties can be achieved without significantly damaging the fiber. Because the textiles look new longer, they are worn longer and are replaced less quickly. This leads to a reduction in the CO2 footprint, since less polyester is used.

Therefore, in a first aspect, the present invention is directed to a polyesterase which has at least 70% sequence identity with the amino acid sequence given in SEQ ID NO: 1 over its entire length.

In a second aspect, the invention also relates to an agent, in particular a washing or cleaning agent, characterized in that it contains a polyesterase which has at least 70% sequence identity with the amino acid sequence given in SEQ ID NO: 1 over its entire length. In a further aspect, the present invention is directed to methods for cleaning textiles, characterized in that in at least one method step

In another aspect, the present invention further relates to the use of an agent as described herein, preferably a washing or cleaning agent, particularly preferably a liquid detergent, for removing stains.

In addition, a further aspect of the invention includes the use of the polyesterase described herein for reducing pilling effects and / or increasing the anti-gray effect of an agent, preferably a washing or cleaning agent, particularly preferably a liquid detergent, the agent being the Contains polyesterase.

In various embodiments of the invention, the polyesterase comprises one

92.5%, 93%, 93.5%, 94%, 94.5%, 95%, 95.5%, 96%, 96.5%, 97%, 97.5%, 98%, 98, 5%, 98.8%, 99.0%, 99.2%, 99.4% or 99.6% is identical or consists of such a sequence.

In various further embodiments, the polyesterase or the agent containing it is characterized in that

 (a) the polyesterase can be obtained from a polyesterase as defined above as a starting molecule by one or more conservative amino acid substitution; and or

(b) the polyesterase is obtainable as a starting molecule from a polyesterase as defined above by fragmentation, deletion, insertion or substitution mutagenesis and an amino acid sequence which comprises a length of at least 180, 190, 200, 210, 220, 230, 240, 245, 250, 251, 252, 253, 254, 255, 256, 257, 258, 259 or 260 contiguous amino acids corresponds to the starting molecule. The agents according to the invention preferably contain the polyesterase in an amount of 0.00001 to 1% by weight, more preferably in an amount of 0.0001 to 0.5% by weight, particularly preferably in an amount of 0.001 to 0.1 % By weight, based in each case on the active protein.

The identity of 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 (see, for example, Altschul et al. (1990) “Basic local alignment search tool.” J. Mol. Biol. 215: 403-410, and Altschul et al. (1997) "Gapped BLAST and PSI-BLAST: a new generation of protein database search programs"; Nucleic Acids Res. 25: 3389-3402) and happens principally by the fact that similar sequences of nucleotides or amino acids in the nucleic acid or Amino acid sequences can be assigned to each other. A tabular assignment of the relevant positions is called alignment. Another algorithm available in the prior art is the FASTA algorithm. Sequence comparisons (alignments), in particular multiple sequence comparisons, are created using computer programs. For example, the Clustal series (cf. e.g. Chenna et al. (2003) “Multiple sequence alignment with the Clustal series of programs”, Nucleic Acid Res. 31: 3497-3500), T-Coffee (cf. e.g. Notredame) are frequently used et al. (2000) “T-Coffee: A novel method for multiple sequence alignments”, J. Mol. Biol. 302: 205-217) or programs based on these programs or algorithms. Sequence comparisons (alignments) with the computer program Vector NTI® Suite 10.3 (Invitrogen Corporation, 1600 Faraday Avenue, Carlsbad, California) are also possible.

USA) with the specified standard parameters, whose AlignX module for 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 specified in percent identity, that is to say the proportion of identical nucleotides or amino acid residues in the same positions or in an alignment corresponding to one another. The broader term homology refers to

Amino acid sequences conserved amino acid exchanges into consideration, that is, amino acids with similar chemical activity, since they usually have similar chemical activities within the protein. Therefore, the similarity of the compared sequences can also be given in percent homology or percent similarity. Identity and / or

Homology information can be made about 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 a few

Include nucleotides or amino acids. Often such small areas practice for those

Overall activity of the protein has essential functions. It can therefore make sense

Only match sequence matches to individual, possibly small areas. Unless otherwise stated, identity or homology information relates to the present Registration, however, for the total length of the specified nucleic acid or amino acid sequence.

In various embodiments, the polyesterase comprises an amino acid sequence that is at least 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88 across the entire length of the amino acid sequence given in SEQ ID NO: 1 %, 89%, 90%, 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%, 98.8%, 99.0%, 99.2%, 99.4% or 99.6 % is homologous.

In a further embodiment of the invention, the polyesterase is characterized in that its anti-pilling performance compared to that of a polyesterase, the one

Amino acid sequence which corresponds to (or consists of) the amino acid sequence given in SEQ ID NO: 1, is not significantly reduced, i.e. has at least 70%, 75%, 80%, 85%, 90%, 95% of the reference anti-pilling performance. This relates in particular to variants which have the sequence identities or homologies given above. The anti-pilling performance can be determined in a washing system which contains a detergent in a dosage between 4.5 and 7.0 grams per liter of washing liquor and the polyesterase, the polyesterases to be compared being used with the same concentration (based on active protein) and determining anti-pilling performance as described herein. For example, the washing process can take place for 60 minutes at a temperature of 60 ° C and the water has a water hardness between 15.5 ° and 16.5 ° (German hardness). The concentration of the polyesterase in the detergent intended for this washing system is from 0.00001 to 1% by weight, preferably from 0.0001 to 0.5% by weight, particularly preferably from 0.001 to 0.1% by weight, based on active, purified protein.

A preferred liquid detergent for such a washing system is composed as follows (all figures in percent by weight): 4.4% alkylbenzenesulfonic acid, 5.6% anionic surfactants,

2.4% C12-C18 Na salts of fatty acids, 4.4% non-ionic surfactants, 0.2% phosphonates, 1, 4% citric acid, 0.95% NaOH, 0.01% anti-foam, 2% glycerin, 0.08% preservatives, 1% ethanol, 1, 6% enzyme mix (protease, amylase, cellulase, mannanase), remainder demineralized water. The dosage of the liquid detergent is preferably between 4.5 and 6.0 grams per liter of wash liquor, for example 4.7, 4.9 or 5.9 grams per liter of wash liquor. Washing is preferably carried out in a pH range between pH 8 and pH 10.5, preferably between pH 8 and pH 9.

Within the scope of the invention, the anti-pilling performance is determined at 60 ° C. using a liquid detergent as indicated above, the washing process preferably taking place for 60 minutes. The anti-pilling performance can be tracked using visual sampling. In this case, a test group assigns the laundry to be examined a value on a scale of 1-5. The value = 1 stands for very heavily pilled laundry, while the value = 5 is assigned to unpilled laundry.

The use of the respective polyesterase with the same activity ensures that even if the ratio of active substance to total protein (the values of the specific activity) differs, the respective enzymatic properties, for example the anti-pilling performance, are compared. In general, a low specific activity can be compensated for by adding a larger amount of protein.

Proteins can be grouped into groups of immunologically related proteins by reaction 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 are recognized by an antiserum or certain antibodies. Another one

The subject of the invention therefore form polyesterases which are characterized in that they have at least one and, with increasing preference, two, three or four matching antigenic determinants with a polyesterase used in an agent according to the invention. Because of their immunological agreement, such polyesterases are structurally so similar to the polyesterases used in the agents according to the invention that a similar function can also be assumed.

Other polyesterases used in the agents according to the invention can have further amino acid changes, in particular amino acid substitutions, insertions or deletions, compared to the polyesterase described in SEQ ID NO: 1. Such polyesterases are, for example, by targeted genetic modification, i.e. through mutagenesis processes, further developed and optimized for specific purposes or with regard to special properties (for example with regard to their catalytic activity, stability, etc.). Furthermore, nucleic acids encoding the polyesterases used can be introduced into recombination approaches and thus used to generate completely new types of polyesterases or other polypeptides.

The aim is to introduce targeted mutations such as substitutions, insertions or deletions into the known molecules, for example in order to improve the cleaning performance of enzymes according to the invention. For this purpose, in particular the surface charges and / or the isoelectric point of the molecules and thereby their interactions with the substrate can be changed. For example, the net charge of the enzymes can be changed in order to influence the substrate binding, especially for use in detergents and cleaning agents. Alternatively or additionally, the stability of the polyesterase can be further increased by one or more corresponding mutations and its cleaning performance can thereby be improved. Advantageous properties of individual mutations, for example individual substitutions, can complement one another. A polyesterase that has already been optimized with regard to certain properties, for example with regard to its activity and / or its anti-pilling performance, can therefore be further developed within the scope of the invention.

Another object of the invention is therefore a polyesterase, which is characterized in that it is obtainable from a polyesterase as described above as the starting molecule by one or more conservative amino acid substitution. The term "conservative amino acid substitution" means the substitution of one amino acid residue for another amino acid residue, this exchange not leading to a change in polarity or charge at the position of the amino acid exchanged, e.g. the exchange of a non-polar amino acid residue for another non-polar amino acid residue. conservative

Amino acid substitutions within the scope of the invention include, for example: G = A = S, I = V = L = M, D = E, N = Q, K = R, Y = F, S = T, G = A = I = V = L = M = Y = F = W = P = S = T. The homology of the polyesterases modified in this way to the polyesterase with SEQ ID NO: 1 is preferably as defined above.

Alternatively or additionally, the polyesterase is characterized in that it consists of a polyesterase contained in an agent according to the invention as the starting molecule

Fragmentation, deletion, insertion or substitution mutagenesis is available and comprises an amino acid sequence that has a length of at least 180, 190, 200, 210, 220, 230, 240, 245, 250, 251, 252, 253, 254, 255, 256, 257, 258, 259, 260 or 261 connected amino acids coincides with the starting molecule.

In various embodiments, the polyesterases obtainable in this way, even after the mutagenesis / substitution, still have the sequence identities defined here of at least 70% with the sequence according to SEQ ID NO: 1.

So it is possible, for example, on the termini or in the loops of the enzyme individual

To delete amino acids without losing or reducing hydrolytic activity. Furthermore, such fragmentation, deletion, insertion or

Substitution mutagenesis, for example, also reduces the allergenicity of enzymes and thus improves their overall usability. The enzymes advantageously retain their hydrolytic activity even after the mutagenesis, ie their hydrolytic activity corresponds at least to that of the starting enzyme, ie in a preferred embodiment the hydrolytic activity is at least 80%, preferably at least 90%, of the activity of the starting enzyme. Other substitutions can also have beneficial effects. Either single as well as several connected amino acids can be exchanged for other amino acids.

In various embodiments, the polyesterase can have one or more further amino acids in addition to the sequence N- or C-terminal given in SEQ ID NO: 1. In certain embodiments, such N-terminal peptides can be the naturally occurring signal peptides for the polyesterase or a single methionine residue.

An object of the invention is an agent which is characterized in that it contains a polyesterase as defined herein. The agent is preferably a washing or

Cleaning supplies.

In various embodiments, the total amount of surfactants based on the weight of the composition is 2 to 30% by weight, preferably 5 to 25% by weight, more preferably 10 to 20% by weight, most preferably 14 to 18% by weight , wherein the (linear) alkylbenzenesulfonates at most in an amount of 0.001 to 30 wt .-%, preferably 0.001 to 10 wt .-%, further preferably 2 to 6 wt .-%, more preferably 3 to 5 wt .-%, based on the weight of the agent.

Washing or cleaning agents according to the invention can contain further enzymes in addition to the polyesterase. These can be hydrolytic enzymes or other enzymes in a concentration suitable for the effectiveness of the agent. One embodiment of the invention thus represents agents which comprise one or more enzymes. All enzymes which can develop a catalytic activity in the agent according to the invention, in particular a protease, amylase, cellulase, hemicellulase, mannanase, tannase, xylanase, xanthanase, xyloglucanase, β-glucosidase, pectinase, carrageenase, perhydrolase, oxidase, can preferably be used as enzymes , Oxidoreductase or a lipase, and mixtures thereof. Enzymes are in the mean

advantageously each in an amount of 1 x 10 ⁸ to 5 wt .-% based on active protein. Each enzyme is increasingly preferred in an amount of 1 × 10 ⁷ to 3% by weight, from 0.00001 to 1% by weight, from 0.00005 to 0.5% by weight, from 0.0001 to 0 , 1 wt .-% and particularly preferably from 0.0001 to 0.05 wt .-% in agents according to the invention, based on active protein. The enzymes particularly preferably show synergistic cleaning performance against certain soiling or stains, ie the enzymes contained in the composition of the agents mutually support one another in their cleaning performance. synergistic Effects can occur not only between different enzymes, but also between one or more enzymes and other ingredients of the agent according to the invention.

The amylase (s) is preferably an a-amylase. The hemicellulase is preferably a β-glucanase, a pectinase, a pullulanase and / or a mannanase. The cellulase is preferably a cellulase mixture or a one-component cellulase, preferably or predominantly an endoglucanase and / or a cellobiohydrolase. The oxidoreductase is preferably an oxidase, in particular a choline oxidase, or a perhydrolase.

The proteases used are preferably alkaline serine proteases. They act as non-specific endopeptidases, which means that they hydrolyze any acid amide bonds that are inside peptides or proteins and thus cause protein-containing soiling to be broken down on the items to be cleaned. Their pH optimum is usually in the clearly alkaline range.

The protein concentration can be determined using known methods, for example the BCA method (bicinchoninic acid; 2,2'-bichinolyl-4,4'-dicarboxylic acid) or the biuret method. In this regard, the active protein concentration is determined by titrating the active centers using a suitable irreversible inhibitor (for proteases, for example, phenylmethylsulfonyl fluoride (PMSF)) and determining the residual activity (see M. Bender et al.

(1966), J. Am. Chem. Soc. 88 (24): 5890-5913).

In the cleaning agents described herein, the enzymes to be used can also be packaged together with accompanying substances, for example from fermentation. In liquid

Formulations, the enzymes are preferably used as enzyme liquid formulation (s).

As a rule, the enzymes are not provided in the form of the pure protein, but rather in the form of stabilized, storable and transportable preparations. To this

Pre-made preparations include, for example, the solid preparations obtained by granulation, extrusion or lyophilization or, particularly in the case of liquid or gel-like agents, solutions of the enzymes, advantageously as concentrated as possible, low in water and / or mixed with stabilizers or other auxiliaries.

Alternatively, the enzymes can be encapsulated both for the solid and for the liquid administration form, for example by spray drying or extrusion of the enzyme solution together with a preferably natural polymer or in the form of capsules, for example those in which the enzymes are enclosed as in a solidified gel or in those of the core-shell type in which an enzyme-containing core with a water, air and / or Chemical-impermeable protective layer is coated. Additional active ingredients, for example stabilizers, emulsifiers, pigments, bleaching agents or dyes, can additionally be applied in superimposed layers. Capsules of this type are applied by methods known per se, for example by granular or roll granulation or in fluid-bed processes. Such granules are advantageously polymeric, for example by applying them

Film former, low in dust and stable in storage due to the coating.

Furthermore, it is possible to assemble two or more enzymes together, so that a single granulate has several enzyme activities.

In various embodiments, the agent according to the invention can have one or more enzyme stabilizers. The agent according to the invention can therefore also be a

Enzyme stabilizer, for example selected from the group consisting of sodium formate, sodium sulfate, lower aliphatic alcohols and boric acid and their esters and salts. Of course, two or more of these compounds can also be used in combination. The salts of the compounds mentioned can also be used in the form of hydrates, such as, for example, sodium sulfate decahydrate.

In this context, polyols, for example glycerol, (mono) ethylene glycol, (mono) propylene glycol or sorbitol, should be mentioned as belonging to the group of lower aliphatic alcohols, without the invention being restricted to these.

In addition to the at least one enzyme stabilizer selected from the above group, an agent according to the invention can also contain at least one further stabilizer.

Stabilizers of this type are known in the prior art.

Reversible protease inhibitors protect the enzymes contained in a washing or cleaning agent against proteolytic degradation by reversibly inhibiting the enzymatic activity of the proteases contained in the agent. Benzamidine hydrochloride, boronic acids or their salts or esters are frequently used as reversible protease inhibitors, including above all derivatives with aromatic groups, for example ortho, meta or para substituted

Phenylboronic acids, especially 4-formylphenylboronic acid, or the salts or esters of the compounds mentioned. Peptide aldehydes, that is to say oligopeptides with a reduced C-terminus, in particular those of 2 to 50 monomers, are also used for this purpose. The peptide reversible protease inhibitors include, among others, ovomucoid and leupeptin. Further enzyme stabilizers are amino alcohols such as mono-, di-, triethanol- and -propanolamine and their mixtures, aliphatic carboxylic acids up to C12, such as succinic acid, other dicarboxylic acids or salts of the acids mentioned. End-capped fatty acid amide alkoxylates are also suitable for this purpose. Some organic acids used as builders can also stabilize an enzyme. Calcium and / or magnesium salts are also used for this purpose, such as calcium acetate.

Polyamide oligomers or polymeric compounds such as lignin, water-soluble vinyl copolymers or cellulose ethers, acrylic polymers and / or polyamides stabilize the enzyme preparation, among other things, against physical influences or pH fluctuations. Polymers containing polyamine-N-oxide act both as enzyme stabilizers and as

Dye transfer inhibitors. Other polymeric stabilizers are linear Cs-C-is polyoxyalkylenes. Alkyl polyglycosides can also stabilize the enzymatic components of the agent according to the invention and preferably are capable of additionally increasing their performance. Crosslinked N-containing compounds preferably fulfill a double function as soil release agents and as enzyme stabilizers.

Examples

Example 1: Expression

 A synthetic gene with a nucleotide sequence adapted to the Trichoderma codon usage was used for the expression of the polyesterase. The gene was fused with various secretion signals using Gibson assembly and cloned into a plasmid for amplification in Escherichia coli. This expression plasmid has a strong promoter for the expression of the corresponding mRNA of the polyesterase gene and further elements which allow a selection of Escherichia coli cells which have taken up the expression construct after the transformation.

The corresponding construct for transformation and subsequent integration into the genome of Trichoderma reesei was obtained from this plasmid by restriction with Not \. This transformation fragment contains the elements for the expression of the polyesterase gene and a gene which allows the selection of successfully transformed cells in Trichoderma reesei.

After the most productive expression strain had been selected, the polyesterase was produced in sufficient quantity by fermentation in order to be able to be used for washing application tests.

After the 20 experiments, the pili reduction of the pre-pilled tissues and the pili formation of the new tissues are assessed optically.

The pre-pilled fabrics are produced by washing cycles repeated 20 times at 40 ° C in standard washing machines.

After each washing cycle, the complete laundry is dried in the dryer. Washing conditions:

 Water with 16 ° dH, 2.5 kg clean laundry, 40 ° C normal program, 50 ml detergent as described above per machine

 Dosage of the polyesterase to be examined: 50 mg active enzyme per washing machine
