Cut-and-paste DNA transposons of the mariner/Tc1 family are useful tools for genome engineering and are inserted specifically at TA target sites. A crystal structure of the mariner transposase Mos1 (derived from Drosophila mauritiana). in complex with transposon ends covalently joined to target DNA. portrays the transposition machinery after DNA integration. https://www.truvisionhealthftp.com/
