Patent ID: 7183093

Claim:
An isolated mannanase, which is: (a) a polypeptide encoded by the DNA sequence cloned into the plasmid present in Estherichia coli DSM 12441, (b) a polypeptide comprising a sequence of amino acids 33–331 of SEQ ID NO: 12 or a fragment thereof that has mannanase activity, or (c) a polypeptide encoded by a DNA sequence that hybridizes with nucleoticles 97–993 of SEQ ID NO: 11 under high stringency conditions, wherein the hybridization is performed in 5×SSC, 0.5% SDS for 12 hours at 45° C. and then washed twice for 30 minutes in 2×SSC, 0.5% SDS at 70° C.
