<p>Transposons are mobile DNA sequences capable of replication and insertion into the chromosome. Typically transposons code for the transposase enzyme, which catalyses insertion, found between terminal inverted repeats [<cite idref="PUB00020477"/>]. Tn5 has a unique method of self- regulation in which a truncated version of the transposase enzyme acts as an inhibitor [<cite idref="PUB00006439"/>].</p><p>More information about these proteins can be found at Protein of the Month: Transposase [<cite idref="PUB00034633"/>].</p> Transposase Tn5, dimerisation
