Example text

1991, 1993). 1 Tn7 Is Excised from the Donor Backbone by Double-strand Breaks When the recombination substrates are a donor plasmid containing a Tn7 element and a target plasmid containingattTn7, the reaction products are a simple insertion of Tn7 into attTn7 and the donor backbone from which Tn7 has been excised (Fig. 4A). , Tn7 is not copied by DNA replication during the act of transposition. Thus replication is limited to repair of the joints between the newly inserted transposon and the target DNA.

6 The Tn7 Transposition Machinery and Antibiotic Resistance Genes . . . . . . . . . The tns Genes .......................................................... Different Sets of tns Genes Direct Tn7 to Different Types of Target Sites. . . . . . Why Does Tn7 Encode Two Distinct Transposition Pathways? Transposition Substrates: the Ends of Tn7 .................................... Transposition Substrates: Target Selection and Transcription Immunity.

1993). Because TnsC can both stimulate DNA breakage at the transposon ends and provoke joining of the transposon ends to the target DNA. it is suspected that this protein has multiple activities, including the ability to interact with and activate TnsA+B and the ability to interact with the target DNA. TnsC appears to act as a focal point for the regulation of transposition, in particular in evaluating potential target DNAs (see below).
