"isolated mannanase, isolated polynucleotide molecule, expression vector, cultured cell, isolated polypeptide, enzyme preparation. isolated enzyme, processes for making a polypeptide, for improving the properties of cellulosic or synthetic fibers, yarn, woven or nonwoven, for degrade or modify plant material, to process liquid coffee extract and to treat machine tissues, cleaning composition and use of an enzyme preparation or enzyme ". novel mannanases comprising, for example, an amino acid sequence as shown at positions 31 to 330 of sequence id: 2 or their homologues, may be derived, for example, from bacillus sp. 1633 or may be encoded by polynucleotide molecules comprising a nucleotide sequence as shown in sequence: 1, from nucleotide 91 to nucleotide 990, polynucleotide molecules encoding a polypeptide that is at least 65% identical to the amino acid sequence of sequence no. 2, from amino acid residue 31 to amino acid residue 330 or its degenerate nucleotide sequences. The mannanases are alkaline and are usable, for example, in cleaning compositions, in a rupture fluid usable to disrupt an underground formation, to modify a plant material and to treat cellulosic fibers. |
