Transpososome Dynamics and Regulation in Tn10 Transposition

Pages 407-424 | Published online: 11 Oct 2008
 

ABSTRACT

Tn10 is a bacterial transposon that transposes through a non-replicative mechanism. This mode of DNA transposition is widely used in bacteria and is also used by “DNA-based” transposons in eukaryotes. Tn10 has served as a paradigm for this mode of transposition and continues to provide novel insights into how steps in transposition reactions occur and how these steps are regulated. A common feature of transposition reactions is that they require the formation of a higher order protein-DNA complex called a transpososome. A major objective in the last few years has been to better understand the dynamics of transpososome assembly and progression through the course of transposition reactions. This problem is particularly interesting in the Tn10 system because two important host proteins, IHF and H-NS, have been implicated in regulating transpososome assembly and/or function. Interestingly, H-NS is an integral part of stress response pathways in bacteria, and its function is known to be sensitive to changes in environmental conditions. Consequently, H-NS may provide a means of allowing Tn10 to responed to changing environmental conditions. The current review focuses on the roles of both IHF and H-NS on Tn10 transposition.
