Pectic Enzymes

  • Dominic W. S. Wong


Pectic enzymes constitute a unique group of enzymes that catalyze the degradation of pectic polymers in plant cell walls. Depolymerization of pectin is generally associated with the process of fruit ripening. These enzymes therefore play a significant role in the changes occurring in postharvest storage of fruits and vegetables. The control of these enzymes in transgenic tomato fruit has become one of the successful examples in the application of antisense RNA to manipulate gene expression (Kramer et al. 1990).
