摘要:
The present invention relates to method for constructing an expression vector comprising a mutanase gene obtained from a filamentous fungus suitable for heterologous production comprising the steps of a) isolating a DNA sequence encoding a mutanase from a filamentous fungus, b) introducing a kex2-site or kex2-like site between the DNA sequences encoding the pro-peptide and the mature region of the mutanase, c) cloning the DNA sequence obtained in step b) into a suitable expression vector. The invention also relates to a recombinant expression vector comprising said mutanase gene sequence and a kex2 cleavage site between the DNA sequence encoding the pro-peptide and the region encoding the mature mutanase, a filamentous fungus host cell, a process for producing recombinant mutanase and a recombinant mutanase. It is also the object of the invention to provide compositions useful in oral care products for humans and animals.
摘要:
The present invention relates to a polypeptide hybrid comprising an amino acid sequence with binding affinity for mutan bound to an active component useful for oral care purposes, an oral care composition comprising a mutan binding domain, an oral care product comprising such an oral care composition of the invention, and finally the use of a mutan binding polypeptide hybrid or single unit MBD for oral care purposes, including preventing dental plaque formation and/or removal of existing dental plaque.
摘要:
The present invention relates to a cloned DNA sequence encoding an enzyme with dextranase activity, a recombinant expression vector comprising said DNA sequence, a filamentous fungus host cell, a method for producing said recombinant dextranase, and the isolated and purified enzyme. The invention also relates to compositions comprising the recombinant enzyme, oral care compositions and products and the use for removing of dental plaque.
摘要:
The properties of dough or bread can be improved by the addition of a carbohydrate oxidase which can oxidise the reducing end of an oligosaccharide more efficiently than the corresponding monosaccharide, e.g., preferentially oxidizing maltodextrins or cellodextrins over glucose. A novel carbohydrate oxidase having the capability to oxidize maltodextrins and cellodextrins more efficiently than glucose may be obtained from a strain of Microdochium, particulary M. nivale. The amino acid sequence of the novel carbohydrate oxidase has very low homology (∫20 % identity) with known amino acid sequences.
摘要:
The present invention relates to an isolated polypeptide exhibiting phytase activity, the corresponding cloned DNA sequences, a process for preparing the polypeptide, and the use thereof for a number of industrial applications, in particular in animal feed. The novel phytase is derived from Peniophora lycii and has some interesting features, such as high initial affinity for the 6-position of phytic acid, a high initial rate of liberating phosphate from phytic acid and an exceptionally high specific activity.
