CC   -!- FUNCTION: Involved in maceration and soft-rotting of plant tissue.
CC       Hydrolyzes the 1,4-alpha glycosidic bonds of de-esterified pectate in
CC       the smooth region of the plant cell wall (By similarity).
CC       {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(1,4-alpha-D-galacturonosyl)n+m + H2O = (1,4-alpha-D-
CC         galacturonosyl)n + (1,4-alpha-D-galacturonosyl)m.; EC=3.2.1.15;
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the glycosyl hydrolase 28 family. {ECO:0000305}.
