Abstract

Gene fusions that bring expression of the lacZ gene under control of transcriptional and trnaslational signals within the transposable element Tn3 have been used to study regulation of Tn3-specified proteins. A gene encoding a 21,355-Mr peptide that represses translocation of Tn3 and acts at the level oquenced; amber, missense, and cis-dominant (operator-constitutive) point mutations in this gene have been isolated and characterized.
