TransposaseTc1-like (IPR038717) is a DDE domain transposase. Tc1 transposase is a member of the DD[E/D]-transposase family. It has a unique pattern made up of three acidic residues, two of which are aspartic acid and one of which is glutamic acid. In some cases, the third aspartic acid is a [D, D, (E, or D)] motif. The three catalytic residues are in close proximity for catalysis, as members of the DD[E/D]-transposase family share a common RNase H-like structure.
