The assay of ATP-sulfurylase. 1986

F A Hommes, and L Moss

An assay method for ATP-sulfurylase is described, based on the incorporation of 35SO4(2-) into adenosine-5'-phosphosulfate (and 3-phosphoadenosine-5'-phosphosulfate) and the separation of these compounds by HPLC. Since the enzyme is easily inactivated at temperatures above 20 degrees C during the assay, the reaction time should not exceed 10 min.

D010724	Phosphoadenosine Phosphosulfate	3'-Phosphoadenosine-5'-phosphosulfate. Key intermediate in the formation by living cells of sulfate esters of phenols, alcohols, steroids, sulfated polysaccharides, and simple esters, such as choline sulfate. It is formed from sulfate ion and ATP in a two-step process. This compound also is an important step in the process of sulfur fixation in plants and microorganisms.
