Abstract

A method is described for the separation and isolation of two electrophoretically distinct arylsulfatases (arylsulfatase EC.3.1.6.1) from Pseudomonas aeruginosa.Characterization of the enzymes revealed that they were type I arylsulfatases, with similar kinetic properties. They differed, however, in respect to charge, pH optima for substrate hydrolysis, and activation by anions. In addition, the enzymes displayed dual pH optima curves with both substrates used and the curious property of a shift in pH optima with varied p-nitrophenyl sulfate concentrations.
