A method for the purification of arylsulphatase (aryl-sulphate sulphohydrolase, EC of Aspergillus nidulans has been described. The enzyme elutes from DEAE-cellulose in two distinct fractions, designated as Fraction I and Fraction II. Fraction I was purified over 450-fold and Fraction II over 600-fold. The two fractions were characterized with respect to some of their physical and biochemical properties. They differ in their Km values for p-nitrophenyl sulphate and nitrocatechol sulphate, sensitivity to some inhibitors, electrophoretic mobility and heat stability. In most other properties they are similar.
