The inactivation of the synthesis of induced BETA -galactosidase by cells of Escherichia coli by ultraviolet irradiation is described. Synthesis of enzyme can be preferentially restored by photoreactivation. Examination of crude cell extracts by zone electrophoresis revealed the presence of a particle-bound enzyme that did not migrate in the electric field. The particle-bound enzyme is shown to exist only as long as inducer is present. The significance of these observations with respect to the possible mechanism of enzyme synthesis is discussed.
