Mannanases

Abstract

Novel mannanases comprising e.g. an amino acid sequence as shown in positions 31-330 of SEQ ID NO:2 or their homologues may be derived from e.g. Bacillus sp. I633, or may be encoded by polynucleotide molecules comprising a nucleotide sequence as shown in SEQ ID NO: 1 from nucleotide 91 to nucleotide 990, polynucleotide molecules that encode a polypeptide that is at least 65% identical to the amino acid sequence of SEQ ID NO: 2 from amino acid residue 31 to amino acid residue 330, or degenerate nucleotide sequences thereof. The mannanases are alkaline and are useful e.g. in cleaning compositions, in a fracturing fluid useful to fracture a subterranean formation, for modifying plant material, and for treatment of cellulosic fibers.
