Definitions

  • the present invention relates to a novel subtilisin-type alkaline protease from Bacillus pumilus and to sufficiently related proteins and their derivatives. It also relates to detergents and cleaners with this new Subtilisin-type alkaline protease, sufficiently related proteins and their derivatives, corresponding washing and cleaning processes and their use in detergents and cleaners, and other technical uses.
  • Enzymes are well-established active ingredients in detergents and cleaners. Proteases cause the degradation of protein-containing stains on the cleaning material, such as textiles or hard surfaces. At best, there are synergies between the enzymes and the remaining components of the funds concerned.
  • the development of detergent proteases is based on naturally, preferably microbially formed enzymes. Such are optimized by per se known mutagenesis method, for example, point mutagenesis, deletion, insertion or fusion with other proteins or protein parts or other modifications for use in detergents and cleaners.
  • subtilisins occupy an outstanding position due to their favorable enzymatic properties such as stability or pH optimum.
  • subtilisins are attributed to the serine proteases due to the catalytically active amino acids. They are naturally produced and secreted by microorganisms, especially Bacillus species. They act as nonspecific endopeptidases, that is, they hydrolyze any acid amide linkages that are internal to 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 of detergents or cleaners.

  • the enzymes can also be improved with regard to their allergenicity with certain amino acid exchanges or deletions.
  • subtilisins To improve the washing performance of subtilisins, the strategy of inserting additional amino acids into the active loops was followed. This strategy should, in principle, be applicable to all subtilisins belonging to one of subgroups I-S1 (true subtilisins) or I-S2 (highly alkaline subtilisins).
  • Another strategy of performance improvement is to change the surface charges and / or the isoelectric point of the molecules and thereby their interactions with the substrate. Furthermore, point mutants with reduced pH dependent molecular charge variation have been described. From this principle, a method was also derived for the identification of variants, which should be suitable for use in detergents and cleaners; All disclosed variants have at least one exchange in position 103. Generally, variations in the literature are very often described as having an exchange at position 103, optionally combined with a variety of other possible substitutions.
  • An alternative way of improving the performance of detergents and cleaners is to increase the hydrophobicity of the molecules, which may affect the stability of the enzyme. Another way to modulate the performance of proteases is by forming fusion proteins.
  • fusion proteins from proteases and an inhibitor such as the Streptomyces subtilisin inhibitor are disclosed in the literature.

  • a powdered control detergent was a detergent base formulation of the following composition (all figures in weight percent): 10% linear alkylbenzenesulfonate (sodium salt), 1, 5% C 12 -C 18 fatty alcohol sulfate (sodium salt), 2.0% C 12 -C 18 fatty alcohol with 7 EO, 20% sodium carbonate, 6.5% sodium bicarbonate, 4.0% amorphous sodium disilicate, 17% sodium carbonate peroxohydrate, 4.0% TAED, 3.0% polyacrylate, 1, 0% carboxymethylcellulose, 1, 0% phosphonate, 25% sodium sulfate, balance: foam inhibitors, optical brightener, fragrances.
  • the B. pumilus protease according to the invention in pulverulent detergent, especially with respect to cocoa shows a very good washing performance, which is significantly better than the washing performance of Q29ZA8 and B. / enftvs alkaline protease X.

Abstract

L'invention concerne une nouvelle protéase alcaline du type subtilisine issue de Bacillus pumilus, ainsi que des protéines suffisamment apparentées et leurs dérivés. Elle concerne en outre des agents de lavage et de nettoyage contenant cette nouvelle protéase alcaline du type subtilisine, des protéines suffisamment apparentées et leurs dérivés, des procédés de lavage et de nettoyage correspondants, et leur utilisation dans des agents de lavage et de nettoyage.
