ENZYME entry: EC 4.2.2.22

Accepted Name
Pectate trisaccharide-lyase.
Alternative Name(s)
Exopectate-lyase.
Pectate lyase A.
Reaction catalysed
Eliminative cleavage of unsaturated trigalacturonate as the major product from the reducing end of polygalacturonic acid/pectate
Comment(s)
  • Differs in specificity from EC 4.2.2.9 as the predominant action is removal of a trisaccharide rather than a disaccharide from the reducing end.
  • Disaccharides and tetrasaccharides may also be removed.
