  • Title: Plasmids containing one inverted repeat of Tn21 can fuse with other plasmids in the presence of Tn21 transposase.
    Author: Avila P, de la Cruz F, Ward E, Grinsted J.
    Journal: Mol Gen Genet; 1984; 195(1-2):288-93. PubMed ID: 6092854.
    Abstract:
    In the presence of the Tn21 transposase, plasmids that contain a single Tn21 inverted repeat sequence fuse efficiently with other plasmids. This reaction occurs in recA strains, is independent of the transposon-encoded resolution system, and results in insertions into different sites in the recipient plasmid. All fusion products studied contained at least one complete copy of the donor plasmid; most also contained some duplication of it as well. The data are consistent with processive models of transposition.
