The enzyme galacturan 1,4-α-galacturonidase (EC 3.2.1.67) catalyzes the following chemical reaction:

(1,4-α-D-galacturonide)n + H2O (1,4-α-D-galacturonide)n-1 + D-galacturonate

It belongs to the family of hydrolases, specifically those glycosidases that hydrolyse O- and S-glycosyl compounds. The systematic name is poly(1,4-α-D-galacturonide) galacturonohydrolase. Other names in common use include exopolygalacturonase, poly(galacturonate) hydrolase, exo-D-galacturonase, exo-D-galacturonanase, and exopoly-D-galacturonase. This enzyme participates in pentose and glucuronate interconversions and starch and sucrose metabolism.
