Description

Microbulbifer thermotolerans lipase and its use

The present invention is in the field of enzyme technology, in particular the lipolytic action of enzymes on fats and oils, as used, for example, in detergents or cleaners. The invention relates to an agent, in particular washing or cleaning agent, which contains a lipase as defined herein. Furthermore, the present invention relates to a method for cleaning textiles and the use of the

agent according to the invention for the removal of stains.

Lipases are among the most technically important enzymes of all. Their use in detergents and cleaning agents is industrially established and they are contained in virtually all modern, powerful detergents and cleaners. Lipases are enzymes that promote the hydrolysis of

Ester bonds in lipid substrates, especially in fats and oils, catalyze and thus belong to the group of esterases. Lipases are typically enzymes that have a variety of

Substrates can be cleaved, for example, aliphatic, alicyclic, bicyclic and aromatic esters, thioesters and activated amines. Lipases are used to remove fatty

Pollutants used by their hydrolysis (lipolysis) catalyze. Lipases with broad substrate spectra are used in particular where inhomogeneous raw materials or substrate mixtures have to be reacted, that is to say, for example, in detergents

Cleaning agents, since soiling can consist of differently structured fats and oils. The in the known from the prior art washing or

Detergents used lipases are usually of microbial origin and are usually derived from bacteria or fungi, such as the genera Bacillus, Pseudomonas, Acinetobacter, Micrococcus, Humicola, Trichoderma or Trichosporon. Lipases are usually prepared by biotechnological methods known per se by suitable

Microorganisms produced, for example, by transgenic expression hosts of the genera Bacillus or by filamentous fungi.

In the European patent application EP 443063, for example, one for washing and

Detergent lipase from Pseudomonas sp. ATCC 21808. Japanese Patent Application JP 1225490 discloses a Rhizopus oryzae lipase. In general, only selected lipases are suitable for use in liquid surfactant-containing preparations. Many lipases do not show sufficient catalytic performance or stability in such formulations. Especially in washing processes, which are generally carried out at temperatures higher than 20 ^° C, many lipases show thermal instability, which in turn leads to insufficient catalytic activity during the process

Washing process leads. In phosphonate-containing liquid surfactant preparations, this problem is even more serious, for example due to the complex-forming properties of Phosphonates or due to unfavorable interactions between the phosphonate and the lipase.

Consequently, lipase and surfactant-containing liquid formulations of the prior art have the disadvantage that they often do not have satisfactory lipolytic activity in the temperature ranges required by a washing process and therefore are not optimal

Show cleaning performance on lipase-sensitive stains.

Surprisingly, the inventors of the present invention have found that a lipase of Microbulbifer thermotolerans as described herein is active under washing process conditions and has good lipolytic properties. The sequence of the lipase identified herein has no significant sequence homologies to lipases heretofore used in detergents. Therefore, it opens up many possibilities to increase the genetic diversity of commercially used lipases and, if necessary, to change the performance spectrum by mutagenesis.

Therefore, in a first aspect, the present invention is directed to an agent, in particular a detergent or cleaning agent, characterized in that it contains a lipase having at least 65% 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 processes for the purification of textiles, characterized in that in at least one process step

inventive agent is applied.

In yet another aspect, the present invention is further directed to the use of an agent as described herein, preferably a detergent or cleaning agent, more preferably a liquid detergent, for the removal of (greasy) soils.

The lipases according to the invention have enzymatic activity, that is, they are capable of hydrolysing fats and oils, in particular in a washing or cleaning agent. A lipase of the invention is therefore an enzyme which catalyzes the hydrolysis of ester bonds in lipid substrates and thereby is able to cleave fats or oils. Furthermore, a lipase according to the invention is preferably a mature lipase, ie the catalytically active molecule without signal and / or propeptide (s). Unless otherwise stated, the sequences given refer to each mature (processed) enzymes. In various preferred embodiments of the invention, the lipase is a lipase having at least 70% sequence identity with the amino acid sequence given in SEQ ID NO: 1 over its entire length. In further preferred embodiments, the lipase contained in the agent according to the invention comprises or essentially consists of or consists of the amino acid sequence given in SEQ ID NO: 1. In various embodiments of the invention, the invention also encompasses lipases which are derived from the amino acid sequence according to SEQ ID NO: 1, for example by means of mutagenesis. In various other

In embodiments, the invention also encompasses lipases produced by the expression of a

Nucleotide sequence encoding a protein according to SEQ ID NO: 1 are available. In one aspect of the invention, the invention also encompasses nucleotide sequences which correspond to the nucleotide sequence which codes for the protein according to SEQ ID NO: 1 over the total length thereof to at least 66%, 67%, 68%, 69%, 70%, 71%. , 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88 %, 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 %, provided that the native sequence coding for the lipase from Microbulbifer thermotolerans is excluded.

In various embodiments of the invention, the lipase comprises an amino acid sequence which corresponds to the amino acid sequence given in SEQ ID NO: 1 over at least 66% of its total length, 67%, 68%, 69%, 70%, 71%, 72%, 73%. , 74%, 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 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 identical or consists of such a sequence.

In various other embodiments, the means is characterized in that

(a) the lipase is obtainable from a lipase as defined above as the parent molecule by single or multiple conservative amino acid substitution; and or

(b) the lipase is obtainable from a lipase as defined above as the starting molecule by fragmentation, deletion, insertion or substitution mutagenesis and a

A length of at least 205, 210, 220, 230, 240, 245, 250, 260, 270, 280, 290, 300, 301, 302, 303, 304, 305, 306, 307, 308, 309 , 310, 31 1, 312, 313, 314 or 315 contiguous amino acids matches the parent molecule.

The agents according to the invention preferably contain the lipase in an amount of 0.00001-1% by weight, more preferably in an amount of 0.0001-0.5% by weight, particularly preferably in an amount of 0.001-0.1 Wt .-%, each based 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, SF, Gish, W., Miller, W., Myers, EW & Lipman, DJ. (1990) "Basic local alignment search 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 is in principle accomplished by similar sequences of nucleotides or amino acids in the nucleic acid or amino acid sequences of each other be assigned. 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. For example, the Clustal series (see, for example, Chenna et al., 2003, Multiple Sequence Alignment with the Clinical Series of Programs, Nucleic Acid Research 31, 3497-3500), T-Coffee (see, for example, Notredame 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. Also possible are alignment comparisons (alignments) with the computer program Vector NTI® Suite 10.3 (Invitrogen Corporation, 1600 Faraday Avenue, Carlsbad, California, USA) with the default parameters whose AlignX module for sequence comparisons is based on ClustalW.

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, since these usually have similar chemical properties within the protein

Exercise activities. Therefore, the similarity of the compared sequences may also be given in 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. They 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. In various embodiments, the lipase comprises an amino acid sequence that corresponds to the amino acid sequence given in SEQ ID NO: 1 over its total length to at least 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%, 74 %, 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 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% homologous.

In a further embodiment of the invention, the lipase is characterized in that its lipolytic performance is not significantly reduced compared to that of a lipase comprising an amino acid sequence corresponding to the amino acid sequences given in SEQ ID NO: 1, i. has at least 70%, 75%, 80%, 85%, 90%, 95% of the reference benefit. The lipolytic performance can be determined in a washing system containing a detergent in a dosage between 4.5 and 7.0 grams per liter of wash liquor and the lipase, wherein the lipases to be compared are used in the same concentration (based on active protein) and the lipolytic Performance is determined as described herein. For example, the

Washing process for 60 minutes at a temperature of 60 ° C and the water have a water hardness between 15.5 and 16.5 ° (German hardness). The concentration of the lipase 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 weight percent): anionic surfactant 5-7%, builder (eg citric acid and phosphonates) 0-1%, caustic soda 0-1%, palm kernel oil fatty acid 0-1% , Glycerol 0-1%, sodium chloride 1-3%, boric acid 0-1%, other additives (preservative, defoamer, optical brightener, dye, perfume) 0-1% and the rest demineralized water. Preferably, the dosage of the liquid detergent is 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. Preference is given to washing in a pH range between pH 8 and pH 10.5, preferably between pH 8 and pH 9.

In the context of the invention, the determination of the lipolytic performance is carried out at 40 ° C using a liquid detergent as indicated above, wherein the washing process is preferably carried out for 60 minutes.

The degree of whiteness, ie the brightening of soiling, as a measure of the cleaning performance is determined by optical measuring methods, preferably photometrically. A suitable device for this purpose is for example the spectrometer Minolta CM508d. Usually, those for the measurement previously calibrated with a white standard, preferably a supplied white standard.

The activity-like use of the respective lipase ensures that even if the ratio of active substance to total protein (the values of the specific activity) diverge, the respective enzymatic properties, for example the cleaning performance of certain soils, are compared. In general, a low specific activity can be compensated by adding a larger amount of protein.

Otherwise, the lipase activity can also be determined in a customary manner, preferably as described in Bruno Stellmach, "Methods of Determining Enzymes for

Pharmacology, food chemistry, technology, biochemistry, biology, medicine "(Steinkopff Verlag Darmstadt, 1988, p 172ff) .In this case, lipase-containing samples are added to an olive oil emulsion in emulsifier-containing water and incubated at 30 ° C and pH 9.0 In this process, fatty acids are liberated, which are titrated with 0.01 N sodium hydroxide solution over a period of 20 minutes using an autotitrator, so that the pH value remains constant ("pH-stat titration"). Based on the sodium hydroxide consumption, the determination of the lipase activity takes place by reference to a reference lipase sample.

An alternative test for determining the lipolytic activity of the lipases according to the invention is an optical measurement method, preferably a photometric method. The appropriate test involves the lipase-dependent cleavage of the substrate para-nitrophenol butyrate (pNP-butyrate). This is cleaved by the lipase into para-nitrophenolate and butyrate. The presence of para-nitrophenolate can be measured using a photometer, e.g. of the Tecan Sunrise device and the XFLUOR software, at 405 nm, thus allowing a conclusion on the enzymatic activity of the lipase.

Proteins can be grouped into groups of immunologically related proteins by reaction with an antiserum or antibody. The members of such a group are characterized by having the same antigenic determinant recognized by an antibody. They are therefore structurally so similar to each other that they are recognized by an antiserum or specific antibodies. Another one

The subject of the invention is therefore formed by lipases, which are characterized in that they have at least one and increasingly preferably two, three or four identical antigenic determinants with a lipase used in an agent according to the invention.

Such lipases are due to their immunological similarities in the

Lipase according to the invention used structurally so similar that it is assumed that a similar function. Further lipases used in the agents according to the invention may have, in comparison to the lipase described in SEQ ID NO: 1, further amino acid changes, in particular amino acid substitutions, insertions or deletions. Such lipases are, for example, further developed by targeted genetic modification, ie by mutagenesis methods, and optimized for specific applications or with regard to specific properties (for example with regard to their catalytic activity, stability, etc.). Furthermore, nucleic acids encoding the lipases used can be incorporated into recombination approaches and thus used to generate completely new lipases or other polypeptides.

The goal is to introduce into the known molecules targeted mutations such as substitutions, insertions or deletions, for example, to improve the cleaning performance of enzymes of 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. Thus, for example, the net charge of the enzymes can be changed in order to influence the substrate binding, in particular for use in detergents and cleaners. Alternatively or additionally, the stability of the lipase can be further increased by one or more corresponding mutations, thereby improving its cleaning performance. Advantageous properties of individual mutations, e.g. individual substitutions can complement each other. A lipase which has already been optimized with regard to certain properties, for example with respect to its activity, can therefore be further developed within the scope of the invention.

Another object of the invention is therefore an agent containing a lipase, which is characterized in that it is obtainable from a lipase as described above as the starting molecule by one or more conservative amino acid substitution. The term

"conservative amino acid substitution" means the replacement of one

Amino acid residue against another amino acid residue, which exchange does not lead to a change in polarity or charge at the position of the exchanged amino acid, z. B. the replacement of a nonpolar amino acid residue against another nonpolar

Amino acid residue. Conservative amino acid substitutions within the scope of the invention include, for example: G = A = S, l = 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 thus modified lipases to the lipase having SEQ ID NO: 1 is preferably as defined above.

Alternatively or additionally, the lipase is characterized in that it is obtainable from a lipase contained in an agent according to the invention as the starting molecule

Fragmentation, deletion, insertion or substitution mutagenesis and a

Amino acid sequence over a length of at least 205, 210, 220, 230, 240, 245, 250, 260, 270, 280, 290, 300, 301, 302, 303, 304, 305, 306, 307, 308, 309, 310, 31 1, 312, 313, 314, or 315 contiguous amino acids matches the parent molecule.

Thus, for example, it is possible to delete individual amino acids at the termini or in the loops of the enzyme, without this losing or reducing the hydrolytic activity. Furthermore, such fragmentation, deletion, insertion or substitution mutagenesis can also reduce, for example, the allergenicity of the enzymes concerned and thus improve their overall applicability. Advantageously, the enzymes retain even after the

Mutagenesis their hydrolytic activity, i. their hydrolytic activity is at least equal to that of the starting enzyme, i. 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 show beneficial effects. Both single and multiple contiguous amino acids can be substituted for other amino acids.

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

An object of the invention is an agent characterized by containing a lipase as defined herein. The agent is preferably a washing or cleaning agent.

Among the latter, i.a. calculated the fabric softener.

They act as nonspecific endopeptidases, that is, they hydrolyze any acid amide linkages that are located inside peptides or proteins and thereby cause degradation of proteinaceous soils on the items to be cleaned. Their pH optimum is usually in the clearly alkaline range.

The protein concentration can be determined by known methods, for example the BCA method (bicinchoninic acid, 2,2'-biquinolyl-4,4'-dicarboxylic acid) or the biuret method. In this regard, the determination of the active protein concentration takes place via a titration of the active sites using a suitable irreversible inhibitor (for proteases, for example phenylmethylsulfonyl fluoride (PMSF)) and determination of the residual activity (compare M. Bender et al., J. Am. Chem. Soc , 24 (1966), pp. 5890-5913). In the detergents described herein, the enzymes to be used may also be formulated together with adjuncts, such as from fermentation. In liquid formulations, the enzymes are preferably used as enzyme liquid formulation (s).

In deposited layers, further active ingredients, for example stabilizers, emulsifiers, pigments, bleaches or dyes, may additionally be applied. Such capsules are applied by methods known per se, for example by shaking or rolling granulation or in fluid-bed processes. Advantageously, such granules, for example by applying polymeric

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

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

Also calcium and / or magnesium salts are 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, inter alia, against physical influences or pH fluctuations. Polyamine N-oxide-containing polymers act simultaneously as enzyme stabilizers and as

Dye transfer inhibitors. Other polymeric stabilizers are linear Cs-ds polyoxyalkylenes. Also, alkylpolyglycosides can 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 perform a dual function as soil release agents and as enzyme stabilizers.
