ENZYME entry: EC 4.2.2.9

Accepted Name
pectate disaccharide-lyase
Alternative Name(s)
exo-PATE
exopectate lyase
exopectic acid transeliminase
exo-PGL
exopolygalacturonate lyase
exopolygalacturonic acid-trans-eliminase
PATE
pectate exo-lyase
Reaction catalysed
[(1->4)-alpha-D-galacturonosyl](n) <=> 4-(4-deoxy-alpha-D-galact-4-enuronosyl)-D-galacturonate + [(1->4)-alpha-D-galacturonosyl](n-2)
Comment(s)
The enzyme catalyzes the eliminative cleavage of an unsaturated disaccharide from the reducing end of homogalacturonan (the backbone of smooth regions of pectate, also known as de-esterified pectin).
