Inter-plasmid transposition frequencies in the presence and absence of stable transposase docking

Transposase	Target DNA	Stable tpase docking?	Transposition frequencya
HSB5	p5E-Luc	–	400 × 10−8
E2C-L5-SB	p5mE-Luc	−/+	27 × 10−8
E2C-L5-SB	p5E-Luc	+	8 × 10−8
Gal4-L5-SB	p5E-Luc	–	18 × 10−8
Gal4-L5-SB	p5G-Luc	+	4 × 10−8

^aWe divided the number of amp^r/zeo^r/cam^s colonies obtained from three independent transformations by the total number of amp^r colonies.
