Abstract
Alginate lyase activity is exhibited by the amino acid sequences (polypeptides) shown in SEQ ID No:1 and SEQ ID No:2. These polypeptides and their homology equivalents are used to produce 4-deoxy-L-erythro-5-hexoseulose uronic acid (DEH) by contacting the polypeptide(s) with an alginate containing a uronic acid moiety and holding the mixture of the alginate and the polypeptide(s) at a temperature at which alginate lyase activity is exhibited.
