The process whereby an (inducible) enzyme is synthesized in response to a specific molecule (cf. inducer).The inducer molecule (often a substrate that needs the catalytic activity of the inducible enzyme for its metabolism) combines with a repressor and thereby prevents the blocking of an operator by the repressor.
