  • the present invention relates to an improved chemical entity comprising a chemical component linked to an amino acid sequence comprising a Cellulose Binding Domain (CBD) having a binding constant (Kr) for crystalline cellulose (Kr- c) of at least 10 l/gcellulose, and/or a binding constant for Avicel (Kr-av) and/or amorphous cellulose (Kr-am) of at least 1.5 l/gcellulose; and its incorporation in a laundry detergent and/or fabric care composition.
  • CBD Cellulose Binding Domain
  • Modern laundry detergent and/or fabric care compositions contain various detergent ingredients having one or more purposes in obtaining fabrics which are not only clean, fresh and sanitised but also have retained appearance and integrity. Therefore, detergent components such as perfumes, soil release agents, fabric brightening agents, fabric softeners, chelants, bleaching agents and catalysts, dye fixatives and enzymes, have been incorporated in laundry detergent and/or fabric care compositions. In using such detergent components, it is important that some of these compounds deposit on the fabrics so as to be effective during or after the laundering and/or fabric care process.
  • One such example is the use of cellulase enzymes for treatment of fabrics which consist largely of cellulose.
  • the cellulose structures are depolymerized or cleaved into smaller and thereby more soluble or dispersible fractions. This activity in particular on fabrics provides cleaning, rejuvenation, softening and generally improved hand-feel characteristics to the fabric structure.
  • cellulase enzymes it has been difficult to incorporate cellulase enzymes into modern detergents in an effective manner.
  • those skilled in the art have sought to use minimal amounts of cellulase to their fullest effectiveness by ensuring that most, if not all, of the cellulase enzyme comprised in the detergent composition deposits on the fabric.
  • optimum cellulases would generally have a binding domain especially suitable for celluloses. Thus guaranteeing that most of the cellulase enzyme included in the detergent composition will deposit or otherwise bind to the fabric during the laundering cycle to achieve its desired results.

  • WO94/07998 describes cellulase variants of a cellulase classified in family 45, comprising a CBD, a Catalytically Active Domain (CAD) and a region linking the CBD to the CAD, wherein one or more amino acid residues have been added, deleted or substituted and /or another CBD is added at the opposite end of the CAD.
  • W095/16782 relates to the cloning and high level expression of novel truncated cellulase proteins or derivatives thereof in Trichoderma longibrachiatum comprising different core regions with several CBDs.

  • the present invention relates to an improved chemical entity comprising a chemical component which is linked to an amino acid sequence comprising a Cellulose Binding Domain having a binding constant (Kr) for crystalline cellulose (Kr-c) of at least 10 l/gcellulose - preferably at least 20l/gcellulose, and/or a binding constant for Avicel (Kr-av) and/or amorphous cellulose (Kr-am) of at least 1.5 l/gcellulose - preferably 5l/gcellulose.
  • This improved chemical entity has a very high affinity for cellulose and is especially adapted to selectively bind cotton fibers, i.e. crystalline cellulose, Avicel, and/or amorphous cellulose.
  • the present invention further relates to laundry detergent and/or fabric care compositions comprising one or more improved chemical entity(ies). These compositions provide a new, improved and superior, more cost effective performance of the chemical components.

  • the object of the present invention is to increase and/or enhance the performance and cost effectiveness of a chemical component by increasing its deposition ability.
  • This object is achieved by the formulation of an improved chemical entity which comprises a chemical component linked to an amino acid sequence comprising a selected cellulose binding domain. It has been surprisingly found that such improved chemical entities wherein the CBD has been particularly selected for its increased deposition to cellulose, more readily affix or otherwise come into contact with the fabric. Thereby it results in new, greater and/or enhanced performance of the chemical component at the fabric surface or when released during or after the laundry and/or fabric care process. Accordingly, this allows to formulate compositions in a more cost-effective manner, with substantially augmented deposition and hence enhanced benefits of the chemical entity.
  • the present invention encompasses chemical entities with one or more chemical component(s) linked to one or more amino acid sequence(s) comprising one or more cellulose binding domain(s), potentially with one or more linking region(s).
  • CBD Cellulose Binding Domain
  • amino acid sequence comprising a Cellulose Binding Domain are intended to indicate an amino acid sequence capable of effecting binding of the cellulase to a cellulosic substrate (e.g., as described in P. Kraulis et al., Determination of the three-dimensional structure of the C terminal domain of cellobiohydrolase I from Trichoderma reesei. A study using nuclear magnetic resonance and hybrid distance geometry-dynamically simulated annealing. Biochemistry 28:7241-7257, 1989). The classification and properties of cellulose binding domains are presented in P. Tomme et al., in the symposium “Enzymatic degradation of insoluble polysaccharides” (ACS Symposium Series 618, edited by J.N. Saddler and M.H. Penner, ACS, 1995).
  • Cellulose-binding (and other carbohydrate-binding) domains are polypeptide amino acid sequences which occur as integral parts of large polypeptides or proteins consisting of two or more polypeptide amino acid sequence regions, especially in hydrolytic enzymes (hydrolases) which typically comprise a catalytic domain containing the active site for substrate hydrolysis and a carbohydrate- binding domain for binding to the carbohydrate substrate in question.
  • hydrolytic enzymes hydrolases
  • Such enzymes can comprise more than one catalytic domain and one, two or three carbohydrate-binding domains, and they may further comprise one or more polypeptide amino acid sequence regions linking the carbohydrate-binding domain(s) with the catalytic domain(s), a region of the latter type usually being denoted a "linker" or "linking region”.
  • Cellulose-binding domains have also been found in algae, e.g. in the red alga porphyra purpurea in the form of a non-hydrolytic polysaccharide- binding protein [see P. Tomme et al., Cellulose-binding domains - Classification and Properties in Enzymatic Degradation of Insoluble Carbohydrates , John N. Saddler and Michael H. Penner (Eds.), ACS Symposium Series, No. 618 (1996)].

  • cellulose-binding domain is intended to be understood in the same manner as in the latter reference (P. Tomme et al., op. cit. )
  • the P. Tomme et al. reference classifies more than 120 "cellulose-binding domains" into 10 families (l-X) which may have different functions or roles in connection with the mechanism of substrate binding. However, it is to be anticipated that new family representatives and additional families will appear in the future.
  • a CBD may be located at the N or C terminus or at an internal position.
  • the part of a polypeptide or protein (e.g. hydrolytic enzyme) which constitutes a CBD per se typically consists of more than about 30 and less than about 250 amino acid residues.

Brun et al., (1995) Eur. J. Biochem. 231, pp. 142-148; J.B. Coutinho et al., (1992) Molecular Microbiology 6(9), pp. 1243-1252
  • a cellulose binding domain of, e.g. a cellulase several genetic engineering approaches may be used.
  • One method uses restriction enzyme to remove a portion of the gene and then to fuse the remaining gene-vector fragment in frame to obtain a mutated gene that encodes a protein truncated for a particular gene fragment.
  • Another method involves the use of exonucleases such as Ba131 to systematically delete nucleotides either externally from the 5' and the 3' ends of the DNA or internally from a restricted gap within the gene.
  • These gene-deletion methods result in a mutated gene encoding a shortened gene molecule whose expression product may then be evaluated for substrate- binding (e.g. cellulose-binding) ability.
  • substrates for evaluating the binding ability include cellulosic materials such as Avicel TM and cotton fibres.
  • Other methods include the use of a selective or specific protease capable of cleaving a CBD, e.g. a terminal CBD, from the remainder of the polypeptide chain of the protein in question.
