title: Electric field effects on immobilized urease activity.
abstract: The behavior of an enzyme/membrane system containing urease is studied when an external electric field is applied. The device using a potential difference across the enzyme/membrane system is first described. Optimal operating conditions with respect to substrate concentration, ionic strength and pH are studied. Possible mechanisms of the change in membrane activity by electric field are discussed.
