Pectate disaccharide-lyase

The enzyme pectate disaccharide-lyase catalyzes the following process:


 * (1,4-α- D -galacturonosyl)n = (1,4-α- D -galacturonosyl)n–2 + 4-(4-deoxy-α- D -galact-4-enuronosyl)- D -galacturonate

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)-alpha-D-galacturonan reducing-end-disaccharide-lyase. Other names in common use include pectate exo-lyase, exopectic acid transeliminase, exopectate lyase, exopolygalacturonic acid-trans-eliminase, PATE, exo-PATE, and exo-PGL.
