Kinetic studies of the phenol sulphate-phenol sulphotransferase of Aspergillus oryzae.

By G R Burns, E Galanopoulou and C H Wynn

Abstract

Arylsulphatase II of Aspergillus oryzae exhibits both hydrolytic and sulphotransferase activities. The kinetic data suggest the formation of an intermediate covalent enzyme-sulphate complex with transfer of sulphate from donor to acceptor proceeding via a Ping Pong mechanism. The unusual kinetic behaviour when 2-hydroxy-5-nitrophenyl sulphate is the substrate is also consistent with this mechanism
