Expression of the transposase gene tnpA of Tn4652 is positively affected by integration host factor.

Abstract excerpt

Tn4652 is a derivative of the toluene degradation transposon Tn4651 that belongs to the Tn3 family of transposons (M. Tsuda and T. Iino, Mol. Gen. Genet. 210:270-276, 1987). We have sequenced the transposase gene tnpA of transposon Tn4652 and mapped its promoter to the right end of the element. The deduced amino acid sequence of tnpA revealed 96.2% identity with the putative transposase of Tn5041. Homology with...
