Glucuronan lyase

The enzyme glucuronan lyase catalyzes the following process:


 * Eliminative cleavage of (1→4)-β- D -glucuronans to give oligosaccharides with 4-deoxy-β- D -gluc-4-enuronosyl groups at their non-reducing ends. Complete degradation of glucuronans results in the formation of tetrasaccharides.

This enzyme belongs to the family of lyases, specifically those carbon-oxygen lyases acting on polysaccharides. The systematic name of this enzyme class is (1→4)-β- D -glucuronan lyase. This enzyme is also called (1,4)-β- D -glucuronan lyase.
