Chondroitin B lyase

The enzyme chondroitin B lyase catalyzes the following process:


 * Eliminative cleavage of dermatan sulfate containing (1→4)-β- D -hexosaminyl and (1→3)-β- D -glucurosonyl or (1→3)-α- L -iduronosyl linkages to disaccharides containing 4-deoxy-β- D -gluc-4-enuronosyl groups to yield a 4,5-unsaturated dermatan-sulfate disaccharide (ΔUA-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.
