Application

Petctinase from Aspergillus niger has been used:
  • for protoplasts liberation
  • in the protoplast enzyme mixture for enzyme digestion
  • to conduct partial saccharification of sugars
  • to 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.

Protocols

Enzymatic Assay of Pectinase

To measure pectinase activity, a titrimetric stop reaction assay is used. One unit of pectinase will liberate 1 μmol of galacturonic acid from poly-galacturonic acid per hour at pH 4.0 at 25 °C.

果胶酶的酶促检测

在测定果胶酶活性时，使用了一种滴定终止反应法进行测定。在25 °C、pH 4.0条件下，一个单位的果胶酶每小时可从多聚半乳糖醛酸释放1 μmol 的半乳糖醛酸。
