Pectate trisaccharide-lyase

Pectate trisaccharide-lyase (, exopectate-lyase, pectate lyase A, PelA) is an enzyme with systematic name (1→4)-α- D -galacturonan reducing-end-trisaccharide-lyase. This enzyme catalyses the following chemical reaction:


 * eliminative cleavage of unsaturated trigalacturonate as the major product from the reducing end of polygalacturonic acid/pectate

The predominant action of this enzyme is removal of a trisaccharide.
