Tn7 transposition: a multigene process. Identification of a regulatory gene product.


Tn7 transposition is abolished by the deletion of a 2.2kb HindIII fragment from the central region of the transposon. Transposition is restored when the fragment is present in trans. When this fragment is present in trans with wild-type Tn7, transposition frequencies are stimulated 10-100-fold. The DNA sequence of this fragment has been determined and found… (More)
