Pectate trisaccharide-lyase (EC 4.2.2.22 exopectate-lyase pectate lyase A PelA) is an enzyme with system name (1->4)-alpha-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/pectateThe predominant action of this enzyme is removal of a trisaccharide.
