일반 설명

Acid phosphatase from potatoes is a 111 kDa diner consisting of two subunits at 41 and 35 kDa. This phosphatase has also been shown to cleave DNA. [1]

애플리케이션

Phosphatase acid from potato has been used in a study to develop a method of efficient enzymatic hydrolysis of polyprenyl pyrophosphates. [2] It has also been used in a study to investigate the kinetics of the hydrolysis of sodium p-nitrophenylphosphate and other phosphoric acid monoesters. [3]

생화학적/생리학적 작용

Acid phosphatases (APase) are a family of enzymes that non-specifically catalyze the hydrolysis of monoesters and anhydrides of phosphoric acid to produce inorganic phosphate at an optimum pH of 4 to 7.

단위 정의

One unit will hydrolyze 1.0 μmole of p-nitrophenyl phosphate per min at pH 4.8 at 37 °C.

A method of efficient enzymatic hydrolysis of polyprenyl pyrophosphates was established. Polyprenyl pyrophosphates such as all-trans-octaprenyl and all-trans-nonaprenyl (solanesyl) pyrophosphate can be hydrolyzed completely to the corresponding primary alcohols by the action of potato acid phosphatase in the presence of
