The enzyme chondroitin B lyase () catalyzes the following process:
Eliminative cleavage of dermatan sulfate containing (1âÂÂ4)-ò-<small>D</small>-hexosaminyl and (1âÂÂ3)-ò-<small>D</small>-glucurosonyl or (1âÂÂ3)-ñ-<small>L</small>-iduronosyl linkages to disaccharides containing 4-deoxy-ò-<small>D</small>-gluc-4-enuronosyl groups to yield a 4,5-unsaturated dermatan-sulfate disaccharide (ÃÂUA-GalNAc-4S).
Glossary:
This enzyme belongs to the family of lyases, specifically those carbon-oxygen lyases acting on polysaccharides. The systematic name of this enzyme class is chondroitin B lyase. Other names in common use include chondroitinase B, ChonB, and ChnB.
