Patent ID: 7329524

Claim:
An isolated agarase which comprises the amino acid sequence of 772 residues from residue 318 to residue 1089 in the amino acid sequence of SEQ ID NO:23, or an amino acid sequence that is encoded by a DNA which hybridizes to the nucleotide sequence of 2316 nucleotides from nucleotide 952 to nucleotide 3267 in the nucleotide sequence of SEQ ID NO:21 in a solution containing 6×SSC (1×SSC: 0.15M NaCl, 0.015M sodium citrate, pH 7.0), 0.5% SDS, 5×Denhardt's and 100 mg/ml herring sperm DNA at 65° C. and has an activity of hydrolyzing an α1,3 bond between 3,6-anhydro-L-galactose and D-galactose in agarose.
