The assay of ATP-sulfurylase.
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.
