Yeast plasmid 2-micron circle promotes recombination within bacterial transposon Tn5.

RESUMO

The site-specific recombination system (FLP) encoded by the yeast plasmid 2-micron circle can also act in yeast on the inverted repeats of the bacterial transposon Tn5. The efficiency of this recombination is dependent on the location of Tn5 within the 2-micron circle genome but can be as high as that observed for 2-micron circle itself. Comparison of the DNA sequences between the Tn5 repeat and the 2-micron circle recombination region reveals certain strikingly similar structural features that might be important in the recombination reaction.
