Definitions

  • the present invention relates to new alkaline protease variants.
  • these In the counting of the alkaline protease from Bacillus lentus, these have variations in amino acid position 61, positions 199 and / or 211 and optionally at least one modification which contributes to stabilizing the molecule, preferably point mutations in positions 3 and / or 4.
  • the present invention also relates to the possible uses of these enzymes in various technical processes and in particular washing and cleaning agents with these new alkaline protease variants.
  • Proteases of the subtilisin type are attributed to the serine proteases due to the catalytically active amino acids. They are naturally formed and secreted by microorganisms, in particular by ßac /// t / s species. They act as non-specific endopeptidases, which means that they hydrolyze any acid amide bonds that are inside peptides or proteins. Their pH optimum is usually in the clearly alkaline range. An overview of this family is provided, for example, by the article "Subtilases: Subtilisin-like Proteases" by R. Siezen, pages 75-95 in "Subtilisin enzymes", edited by R. Bott and C. Betzel, New York, 1996. Subtilisins are suitable for a variety of technical uses, as components of cosmetics and especially as active ingredients in detergents or cleaning agents.
  • Proteases are used alongside other enzymes such as amylases, lipases or cellulases as active components in detergents and cleaning agents. They have the ability to break down protein-based soiling on the items to be cleaned, such as textiles or dishes. Due to their higher solubility, the hydrolysis products are washed out with the washing liquor or attacked, dissolved, emulsified or suspended by the other detergent or cleaning agent components. This can result in synergy effects between the enzymes and the other constituents of the detergents and cleaning agents in question.
  • subtilisins take due to their favorable enzymatic properties such as stability or pH optimum. The most important of these and the most important strategies for their technical development are listed below.
  • the basic strategy in the development of detergent proteases is to first isolate enzymes that are naturally formed microbiologically and to test their basic suitability for this application. Optimizations can then be carried out on these molecules.
  • Bacillus spec. Protease 164-A1 available from 164-A1 from Chemgen Corp., Gaithersburg, MD, USA, and Vista Chemical Company, Austin, TX, USA are suitable for use in detergents and cleaning agents.

  • Subtilisin BPN ' serves, in particular with regard to the numbering of the positions, as a reference enzyme for the subtilisins.

Below this is only position 217, which corresponds to position 211 in enzymes according to the invention; no particular exchange is particularly emphasized for this; all are specified, except for the substitution against M, W, C or K; preferably against A or S.

Since BPN 'naturally has I in position 205 (corresponding to 199), a maximum of these two positions can be considered here as described above, but always in combination with other mutations in loop regions of the subtilisin and with specific changes in the enzymatic properties. Detergents with such BPN 'variants are disclosed, for example, in patent application WO 95/29979 A1.

Variants of this enzyme obtained by point mutation and which are suitable for use in detergents and cleaning agents are disclosed, for example, in the applications WO 94/02618 A1 and EP 328229 A1. In the first, only exchanges in position 211 for different amino acids, but not for D, are described. The second document discloses that certain areas in which the two residues 61 and 211 are also involved in the substrate binding. However, 61 is not listed among the positions of particular interest for mutagenesis, and an exchange for Y is proposed for 211, which, however, can only increase the washing performance of a corresponding formulation in combination with at least one further exchange.

  • subtilisin DY was originally developed by Nedkov et al. 1985 in ß / ' o /. Chem Hoppe-Seyler, Volume 366, pp. 421-430.
  • it can be optimized for use in detergents and cleaning agents via targeted point mutations in the active loops. This gives rise to variants with reduced adsorption and increased hydrolysis rate, including those with exchanges in position 62 (corresponding to 61 in the ⁇ / etrtus alkaline protease) from G to N, D, Q, E, P or S, in position 204 (corresponding to 199), but not 204I and numerous in position 216 (corresponding to 211), including D.

Otherwise, it is only slightly similar to the protease variants according to the invention: at the amino acid level, only a homology value of 30% identity or 38% of similar amino acids can be determined.

  • subtilisins In order to improve the washing performance of the subtilisins, the strategy of inserting additional amino acids into the active loops was pursued in numerous applications, for example in addition to the aforementioned WO 99/27082 A1, also for the applications which are listed under the numbers WO 00/37599 A1, WO 00/37621 A1 to WO 00/37627 A1 and WO 00/71683 A1 to WO 00/71691 A1 have been published.

  • subtilisin variants emerge as can be obtained by a method of application WO 00/24924 A2: they all contain at least one exchange in position 103, combined with a large number of other possible exchanges, but none of them in the position corresponding to position 61 of the protease from ß. lentus corresponds. Multiple variants with at least six exchanges are preferred, including positions 205 and 217 (corresponding to 199 and 211 in the beta / erectus alkaline protease); specifically, only two of more than 50 of these variants have the exchange 1991 relevant for the present application.

  • a modern direction of enzyme development is to combine elements from known, related proteins by statistical methods to new enzymes that have previously unattained properties.
  • Such processes are also summarized under the generic term Directed Evolution. These include, for example, the following methods: the StEP method (Zhao et al. (1998), Nat.

(2001), Nat. Biotechnol , Volume 19, pp. 354-359).
  • Another, in particular complementary, strategy is to increase the stability of the proteases in question and thus to increase their effectiveness.
  • Stabilization via coupling to a polymer has been described for proteases which are used in cosmetics, for example in US Pat. No. 5,230,891; it goes hand in hand with better skin tolerance.
  • stabilization by point mutations is more common, especially for detergents and cleaning agents.

  • Other described options for stabilization via point mutagenesis are, for example:
  • subtilisins can be stabilized and their contribution to the washing or cleaning performance improved by (1.) replacing amino acids of the calcium binding sites with more negative ones, (2.) deleting or mutating natural consequences of Asn-Gly, (3. ) Met residues are exchanged for others and (4.) certain amino acids are also substituted that are close to the catalytic center. None of the first three options apply to the variants of the present application according to the invention. Items 61 and 211 are affected by the fourth option. However, it is proposed here to replace the amino acids naturally occurring in these positions (S63, or Y217 in the case of subtilisin BPN ') by G or L, respectively. In contrast, in the molecules of the present application it is precisely these positions which are occupied by amino acids other than G or L.

When developing them, the possibly calculable enzymatic properties cannot readily be used to infer the behavior of these enzymes, for example in the context of a detergent or cleaning agent formulation. Other factors such as stability against high temperatures, oxidizing agents, denaturation by surfactants, folding effects or desired synergies with other ingredients play a role here, which can often only be developed experimentally.

It should also be taken into account that different codon triplets can code for the same amino acids, so that a certain amino acid sequence can be derived from several different and possibly only slightly identical nucleotide sequences (degeneracy of the genetic code). In addition, different organisms have differences in the use of these codons. For these reasons, both amino acid sequences and nucleotide sequences have to be included in the consideration of the protected area, and specified nucleotide sequences are only to be regarded as exemplary coding for a specific amino acid sequence.
