CC   -!- FUNCTION: Pectinolytic enzymes consist of four classes of enzymes:
CC       pectin lyase, polygalacturonase, pectin methylesterase and
CC       rhamnogalacturonase. Degrades the rhamnogalacturonan I (RG-I) backbone
CC       of pectin (By similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Endotype eliminative cleavage of L-alpha-rhamnopyranosyl-
CC         (1->4)-alpha-D-galactopyranosyluronic acid bonds of
CC         rhamnogalacturonan I domains in ramified hairy regions of pectin
CC         leaving L-rhamnopyranose at the reducing end and 4-deoxy-4,5-
CC         unsaturated D-galactopyranosyluronic acid at the non-reducing end.;
CC         EC=4.2.2.23;
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the polysaccharide lyase 4 family.
CC       {ECO:0000305}.
