Abstract
Fusions that bring lac gene expression under the control of transcriptional and translational signals within the Tn3 element have been used to identify and characterise a Tn3-encoded 'transposase' (Tnp) peptide of MW 100,000 essential for transposition. The gene specifying this product is regulated by the Tn3 repressor protein and is part of a bidirectional genetic unit that includes the repressor gene.
