The regulation of the LIV-I transport system has been investigated. The role of the leucine-coding leader peptide gene of the co-cistronic leucine-isoleucine-valine binding protein gene, livJ, has been examined by site-directed mutagenesis and fusion of the regulatory segment of the livJ gene to the gene coding for $\beta$-galactosidase, lacZ. The results show that the leader peptide gene functions to regulate expression of livJ in the presence of exogenous leucine. A mutation that alters the leader
