EC - Pectate trisaccharide-lyase

  IntEnz view ENZYME view

IntEnz Enzyme Nomenclature


Accepted name:
pectate trisaccharide-lyase
Other names:
pectate lyase A
Systematic name:
(1→4)-α-D-galacturonan reducing-end-trisaccharide-lyase



Differs in specificity from EC, pectate disaccharide-lyase, as the predominant action is removal of a trisaccharide rather than a disaccharide from the reducing end. Disaccharides and tetrasaccharides may also be removed [2].
