DE   exo-poly-alpha-digalacturonosidase.
AN   exo-poly-alpha-galacturonosidase.
AN   exopolygalacturanosidase.
CA   [(1->4)-alpha-D-galacturonosyl](n) + H2O = [(1->4)-alpha-D-
CA   galacturonosyl](n-2) + alpha-D-galacturonosyl-(1->4)-D-galacturonate.
CC   -!- The enzyme, characterized from bacteria, hydrolyzes the second alpha-
CC       1,4-glycosidic bond from the non-reducing end of polygalacturonate,
CC       releasing digalacturonate.
