We constructed plasmid pAtrp46 in which lacZ gene expression is regulated by the attenuator of the Escherichia coli tryptophan (trp) operon. The attenuation of trp, which occurs in the presence of an excess of tryptophan, is reflected by a decrease in the expression of the lacZ gene of pAtrp46 in a
