It is mobilized by a transposase enzyme that catalyses DNA cleavage and integration at short specific sequences at the transposon ends. To facilitate SB's applications, here we determine the crystal structure of the transposase catalytic domain and use it to model the SB transposase/transposon end/target DNA complex. Together with biochemical and cell-based transposition assays, our structure reveals mechanistic insights into SB transposition and rationalizes previous hyperactive transposase mutations. Moreover, our data enables us to design two additional hyperactive transposase variants. Our work provides a useful resource and proof-of-concept for structure-based engineering of tailored SB transposases. Sleeping Beauty transposase structure allows rational design of hyperactive variants for genetic engineering.,Voigt F, Wiedemann L, Zuliani C, Querques I, Sebe A, Mates L, Izsvak Z, Ivics Z, Barabas O Nat Commun. 2016 Mar 30;7:11126. doi: 10.1038/ncomms11126.
