    摘要: The present invention relates to Bacillus hosts transformed with a vector comprising a DNA sequence encoding for a cellulose binding domain (CBD) and capable of expressing said sequence, the expressed polypeptide protein consisting essentially of one or more non-catalytic domains; the cellulose binding domain having a molecular weight in the range of from 4 kD to 35 kD and being obtainable from a microorganism or from a plant, preferably from a bacterium or a fungus; the Bacillus host e.g. being one of the species Bacillus subtilis, Bacillus licheniformis, Bacillus megaterium, Bacillus stearothermophilos, and Bacillus amyloliquefaciens; and a Bacillus expression vector carrying an inserted DNA sequence encoding for a cellulose binding domain; and a method for producing a cellulose binding domain polypeptide in a Bacillus host cell.

    摘要: A xyloglucanase having a relative xyloglucanase activity of at least 50% at pH 7 and either no or an insignificant cellulolytic activity is obtainable e.g. from a strain of Bacillus. A xyloglucanase comprising an amino acid sequence as shown in positions 30-261 of SEQ ID NO:2 or homologues may be derived from eg Bacillus licheniformis, ATCC 14580, and may be encoded by polynucleotide molecules comprising a nucleotide sequence as shown in SEQ ID NO:1 from nucleotide 88 to nucleotide 783; and a xyloglucanase comprising an amino acid sequence as shown in positions 1-537 of SEQ ID NO:4 or homologues may be derived from eg B. agaradhaerens, NCIMB 40482, and may be encoded by polynucleotide molecules comprising a nucleotide sequence as shown in SEQ ID NO:3 from nucleotide 1 to nucleotide 1611. The xyloglucanases are useful e.g. in cleaning compositions and for treatment of cellulosic fibres.
