Patent ID: 7410786

Claim:
An isolated polypeptide which is an enzyme having the activity of degrading β1-6 bonds and β1-4 bonds between D-sulfated galactose or galactose and D-sulfated galactose or galactose in a sulfated fucogalactan, which is selected from the group consisting of: (a) a polypeptide comprising the amino acid sequence of SEQ ID NO:28; and (b) a polypeptide encoded by a nucleic acid capable of hybridizing to the nucleotide sequence of SEQ ID NO:27 or a complete complementary strand thereof under the stringent conditions of 6×SSC (1×SSC: 0.1M NaCl, 0.015M sodium citrate, pH 7.0) containing 5× Denhardt's reagent, 0.5% SDS, 100 μg/ml denatured, fragmented salmon sperm DNA at 68° C. for 12-20 hours, and washing in 2×SSC containing 0.1% SDS at room temperature while changing the SSC concentration to 0.1×SSC and the temperature to 68° C.
