Polygalacturonases (PGs) catalyze the enzymatic depolymerization of pectins – polysaccharides that comprise the plant cell wall. Polymer disassembly of substrates by exo- and endo- PGs is carried out via a hydrolytic mechanism. Degradation of pectins in plant cell walls contributes to ripening of fruits, such as tomatoes and melons (Polygalacturonases: many genes in search of a function).
