Description
In enzymology, a pectate disaccharide-lyase (EC 4.2.2.9) is an enzyme that catalyzes the chemical reaction: Eliminative cleavage of 4-(4-deoxy-alpha-D-galact-4-enuronosyl)-D-galacturonate from the reducing end of pectate, i.e. de-esterified pectin. This enzyme belongs to the family of lyases, specifically those carbon-oxygen lyases acting on polysaccharides.
