ペクチナーゼ

外観

白色～褐色粉末～結晶

解説

ペクチン，ペクチン質に作用する酵素としては，プロトペクチンからのペクチン生成を触媒するプロトペクチナーゼが知られ，ペクチンエステラーゼはペクターゼとも呼ばれ，ペクチンを加水分解してペクチン酸を生成する反応を触媒する。また，ペクチンポリガラクツロナーゼは，ペクチナーゼとも呼ばれ，通常はペクチン酸の加水分解に作用し，ペクチニン酸を分解するものはポリガラクツロナーゼと呼ばれる。

用途

製造用剤

使用

Pectinase, Aspergillus niger is used in plant protoplast preparation to digest cell wall prior to organelle isolation. Pectinase helps facilitate the maceration of plant materials and extraction processes including organelle preparation. It is used in the enzyme preparation. Used mostly to reduce viscosity, to improve filtration to clarify products, to avoid particle sedimentation and to prevent pectin gel formation in the manufacture of fruit juice and wine.

一般的な説明

This product has been enhanced for energy efficiency and waste prevention when used in cellulosic ethanol research.

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.
