Induced enzyme
Inducible enzyme, an enzyme that can be detected in a growing culture of a microorganism, after the addition of a particular substance (inducer) to the culture medium, but was not detectable prior to the addition and can act on the inducer. A prototype is the beta-Galactosidase of escherichia coli, synthesised upon the addition of various galactosides, whether or not these are good substrates.
Compare: constitutive enzyme.
Synonym: adaptive enzyme.
