Pectin lyase

In enzymology, a pectin lyase also known as pectolyase is a naturally occurring pectinase a type of enzyme that degrades pectin. It is produced commercially for the food industry from fungi and used to destroy residual fruit starch, known as pectin, in wine and cider. In plant cell culture, it is used in combination with the enzyme cellulase to generate protoplasts by degrading the plant cell walls.
