The endopolygalacturonase II belongs to the family of | The endopolygalacturonase II belongs to the family of glycoside hydrolases, enzymes that hydrolyse glycosidic bonds in polysaccharidic chains and release smaller sugars, classified in the EC 3.2.1.x group. Within this family, endopolygalacturonases are pectinases, enzymes involved in the degradation of pectin, a polymer of galacturonic acid and rhamnose that is the jelly-like component of plant cell walls. | ||
Endopolygalacturonase II is part of the family 28 of glycoside hydrolases. It is not the only endopolygalacturonase from A. niger - a family of seven genes encode such enzymes, and six different proteins have been identified: endopolygalacturonases I, II, A, B, C and E. | Endopolygalacturonase II is part of the family 28 of glycoside hydrolases.
