CC   -!- FUNCTION: Pectinolytic enzymes consist of four classes of enzymes:
CC       pectine lyase, polygalacturonase, pectin methylesterase and
CC       rhamnogalacturonase. Hydrolyzes alpha-D-galacturonopyranosyl-(1,2)-
CC       alpha-L-rhamnopyranosyl linkages in the backbone of the hairy regions
CC       of pectins (By similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Endohydrolysis of alpha-D-GalA-(1->2)-alpha-L-Rha glycosidic
CC         bond in the rhamnogalacturonan I backbone with initial inversion of
CC         anomeric configuration releasing oligosaccharides with beta-D-GalA at
CC         the reducing end.; EC=3.2.1.171;
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the glycosyl hydrolase 28 family. {ECO:0000305}.
