| + | [https://www.uniprot.org/uniprot/TN5P_ECOLX TN5P_ECOLX] Mediates transposition of transposon Tn5 by a 'cut and paste' mechanism. First, the monomeric transposase binds the 19 bp inverted DNA repeats flanking the transposon. Then, dimerization of the DNA-bound transposase creates a synaptic DNA complex. After nicking of the first DNA strand, excision of the transposon proceeds through a series of intermediates. The transposase then mediates the insertion of the transposon at a new site by strand transfer. The activity of the wild-type transposase is very low, and is further inhibited by dimerization with the transposase inhibitor (inh).<ref>PMID:6260374</ref> <ref>PMID:6291786</ref> <ref>PMID:6303899</ref> <ref>PMID:1310499</ref> <ref>PMID:8226636</ref> <ref>PMID:8871560</ref> <ref>PMID:11877443</ref> <ref>PMID:12367522</ref> | ||
