Description

Description générale

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency and waste prevention when used in cellulosic ethanol research. For more information see the article in biofiles and Enzymes for Alternative Energy Research.

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.

Actions biochimiques/physiologiques

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.

Définition de l'unité

One unit will liberate 1.0 μmole of galacturonic acid from polygalacturonic acid per min at pH 4.0 at 25 °C.

Forme physique

Solution in 40% glycerol
