Exo-poly-α-galacturonosidase (EC 3.2.1.82, exopolygalacturonosidase, exopolygalacturanosidase, poly(1,4-α-D-galactosiduronate) digalacturonohydrolase) is an enzyme with systematic name poly[(1→4)-α-D-galactosiduronate] digalacturonohydrolase.^[1]^[2]^[3] It catalyses the hydrolysis of pectic acid from the non-reducing end, releasing digalacturonate.
