General description

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 used as enzyme for alternative energy. For more information see the Enzymes for Alternative Energy Research.

Application

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.

Biochem/physiol Actions

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

Unit Definition

One unit will release 1.0 microequivalent of acid from pectin per min at pH 7.5 at 30 °C.

Physical form

Contains (NH4)2SO4 and sodium chloride

Analysis Note

Plant organs are produced from meristems in a characteristic pattern. This pattern, referred to as phyllotaxis, is thought to be generated by local gradients of an information molecule, auxin. Some studies propose a key role for the mechanical properties of

Many plants release airborne volatile compounds in response to wounding due to pathogenic assault. These compounds serve as plant defenses and are involved in plant signaling. Here, we study the effects of pectin methylesterase (PME)-generated methanol release from wounded plants
