Exo-poly-alpha-galacturonosidase
Exo-poly-alpha-galacturonosidase (, exopolygalacturonosidase, exopolygalacturanosidase, poly(1,4-alpha-D-galactosiduronate) digalacturonohydrolase) is an enzyme with systematic name poly((1->4)-alpha-D-galactosiduronate) digalacturonohydrolase. This enzyme catalyses the following chemical reaction
Hydrolysis of pectic acid from the non-reducing end, releasing digalacturonate
