Polygalacturonase Activity in the Ripening Tomato Fruitle lamellae. The middle lamellae consist largely of pectin that is degraded by the combined actions of pectinesterase (E.C.3.1.1.11) and poly galacturonase (E.C.3.2.1.15). The former enzyme removes the methyl groups from the polyuronide chain, whereupon the latter enzyme depolymerizes the polygalact

Conceptually, there are many ways in which cohesion could be lost and a subset of these would explain the increase in concentration of cold water soluble pectin which is observed in most, if not all softening fruits.
