Summary
This paper reports a cleavage site map of Tn5 for restriction enzymes BamHI, BglI, BglII, HindII, HindIII, HpaI, SalI, AvaI, SmaI, XhoI, PstI, PvuII, HaeII and HaeIII that was determined by the analysis of restriction enzyme cleavage patterns of ColEl, two independent ColE1::Tn5 plasmids, and a ColE1::Tn5 deletion derivative. BalI, EcoRI, KpnI, and PvuI do not cleave Tn5. Construction and analysis of in vitro-generated deletions of a ColE1::Tn5 plasmid limit the sequences encoding neomycin resistance to a 1500-base-pair-long segment of Tn5. Insertion of DNA at a BglII site within this segment results in loss of the neomycin resistance phenotype. Since this BglII site lies in an inverted repeat region, sequences within this repeat seem to be involved in the expression of neomycin resistance.
