Pectinase enzymes used today are naturally produced by fungi and yeasts (50%), insects, bacteria and microbes (35%) and various plants (15%), [4] but cannot be synthesized by animal or human cells. [5] In plants, pectinase enzymes hydrolyze pectin that is found in the cell wall, allowing for new growth and changes to be made.
These enzymes degrade complex organic matter such as cellulose and hemicellulose into simple sugars that enzyme-producing organisms use as a source of carbon, energy, and nutrients. [2] Grouped as hydrolases, lyases, oxidoreductases and transferases, [1] these extracellular enzymes control soil enzyme activity through efficient degradation of ...
Recent studies [citation needed] have shown that the manipulation of pectinesterase expression can influence numerous physiological processes. In plants, pectinesterase plays a role in the modulation of cell wall mechanical stability during fruit ripening, cell wall extension during pollen germination and pollen tube growth, abscission, stem elongation, tuber yield and root development.
Pectin is composed of complex polysaccharides that are present in the primary cell walls of a plant, and are abundant in the green parts of terrestrial plants. [5] Pectin is the principal component of the middle lamella, where it binds cells. Pectin is deposited by exocytosis into the cell wall via vesicles produced in the Golgi apparatus. [6]
Pectin lyase is a polysaccharide enzyme with a complex structure that is present in plant cell walls. It has a significant role in pectin degradation and different biotechnological and industrial applications. It can be found in many different organisms. [1]
Polygalacturonase is a pectinase, an enzyme that degrades pectin by hydrolyzing the O-glycosyl bonds in pectin's polygalacturonan network, resulting in α-1,4-polygalacturonic residues. [10] The rate of hydrolysis is dependent on polysaccharide chain length.

Pectic acid, also known as polygalacturonic acid, is a water-soluble, transparent gelatinous acid existing in over-ripe fruit and some vegetables.It is a product of pectin degradation in plants, and is produced via the interaction between pectinase and pectin (the latter being common in the wine-making industry.)
