生物活性/药理作用

Pectinesterase catalyzes the hydrolysis of the methyl esters of pectin to yield pectate and methanol.

应 用

Pectinesterase is used to hydrolyze methyl esters of pectin to pectate and methanol. It contains pectin methylesterase and pectin pectylhydrolase. Product P5400 is from orange peel and comes as a lyophilized powder. It contains (NH₄)₂SO₄ and sodium chloride. It has been used to study the pectin methylesterase gene.

The enzyme from Sigma has been used as a standard during the measurement of pectin methylesterase activity in sea buckthorn juices. It has been used in the hydrolysis of cell wall pectins while studying phyllotaxis in Arabidopsis. It has also been used to catalyze pectin hydrolysis (using an ultrasonic measurement device) for monitoring biological processes.

有效单位定义
