Characterization of two hypertransposing Tn5 mutants.


Transposition of Tn5 in Escherichia coli is regulated by two transposon-encoded proteins: transposase (Tnp), promoting transposition preferentially in cis, and the trans-acting inhibitor (Inh). Two separate transposase mutants were isolated that replace glutamate with lysine at position 110 (EK110) and at position 345 (EK345). The EK transposase proteins… (More)
