CC   -!- FUNCTION: Pectinolytic enzyme consist of four classes of enzymes:
CC       pectin lyase, polygalacturonase, pectin methylesterase and
CC       rhamnogalacturonase. Among pectinolytic enzymes, pectin lyase is the
CC       most important in depolymerization of pectin, since it cleaves internal
CC       glycosidic bonds of highly methylated pectins. Favors pectate, the
CC       anion, over pectin, the methyl ester. {ECO:0000269|PubMed:11112543}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Eliminative cleavage of (1->4)-alpha-D-galacturonan to give
CC         oligosaccharides with 4-deoxy-alpha-D-galact-4-enuronosyl groups at
CC         their non-reducing ends.; EC=4.2.2.2;
CC   -!- COFACTOR:
CC       Name=Ca(2+); Xref=ChEBI:CHEBI:29108;
CC         Evidence={ECO:0000269|PubMed:11112543};
CC       Note=Binds 1 Ca(2+) ion per subunit. {ECO:0000269|PubMed:11112543};
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the polysaccharide lyase 1 family.
CC       {ECO:0000305}.
