Pectin lyase

Pectin lyase is a polysaccharide enzyme with a complex structure that is present in plant cell walls.

Pectin lyase is critical for several biological processes, such as the maturation of fruits and reshaping of plant cell walls.

Pectin lyase is crucial to decaying plant materials and is commonly used in the food industry and biotechnology.

The waste residues of citrus, apple, and pomelo and their peels are the major raw resources of pectin production because they are considered by-products of producing juice in the food industry.

Also, it helps protect the plants from the damage that is caused by pathogenic microorganisms due to its rigidity and flexibility.

In (A), we see an overview of the pectin lyase A structure, depicted with arrows for β strands and coils for helices.

It has the ability to efficiently break the pectin molecule's back bone by β-eliminating in order to form pectin-oligosaccharide.

[3][1] In addition, the presence of undesirable enzymatic activity in commercial pectinases may be detrimental to aroma because they are responsible for producing unpleasant volatile off flavor.
