Application

Petctinase from Aspergillus niger has been used: for protoplasts liberation in the protoplast enzyme mixture for enzyme digestion to conduct partial saccharification of sugarsto study their role in the invasion of plant tissues by phytopathogens, the spoilage of produce and various food processing and plant biotechnology applications

Used in plant protoplast preparation to digest cell wall prior to organelle isolation.

Biochem/physiol Actions

Pectolytic enzyme preparation produced from a selected strain of Aspergillus niger: contains mainly pectintranseliminase, polygalacturonase, and pectinesterase and small amounts of hemicellulases and cellulases. Pectinases hydrolyses pectin, which is a component of the cell wall. They may attack methyl-esterified pectin or de-esterified pectin. It is a source of pectinase activity, also containing cellulase and hemicellulase activities.Pectinase catalyzes the random hydrolysis of a-(1-4)-Dgalactosiduronic linkages in pectin and other galacturonans.
