Essential sites at transposon Tn 10 termini

J C Way et al. Proc Natl Acad Sci U S A. 1984 Jun.

Abstract

We describe here point and deletion mutations that define which sequences at the termini of Tn10 are essential for transposition. We conclude that at least 13 and no more than 27 base pairs of terminal IS10 sequence are absolutely required at each end. These sequences correspond closely to the terminal inverted repeats of IS10. Sequences between base pairs 27 and 70 at each terminus and certain non-IS10 sequences can also influence transposition, but to a lesser degree. We also describe properties of many function-defective Tn10 transposition mutants and one exceptional Tn10 mutant.
