A mutant Ebg enzyme that converts lactose into an inducer of the lac operon

S J Rolseth et al. J Bacteriol. 1980 Jun.

Abstract

Lactose is not itself an inducer of the lac operon, nor is it converted to an inducer by ebg+ beta-galactosidase of Escherichia coli. We report here the isolation of a mutant Ebg beta-galactosidase which is capable of converting lactose into an inducer of the lac operon.
