Abstract
Arylsulphatase from seminal plasma of fowl was characterized with a crude enzyme preparation using nitrocatechol sulphate as the substrate. Arylsulphatase activity was considerable and showed a shift of pH optimum dependent on the incubation time and on the presence of sulphate and chloride ions. The electrophoretic pattern of enzymic activity showed three separate bands. It is concluded that both arylsulphatases A and B may be present in seminal plasma.
