Does the proposed DSE motif form the active center in the Hermes transposase?

Abstract excerpt

Donor cleavage and strand transfer are two functions performed by transposases during transposition of class II transposable elements. Within transposable elements, the only active center described, to date, facilitating both functions, is the so-called DDE motif. A second motif, R-K-H/K-R-H/W-Y, is found in the site-specific recombinases of the tyrosine recombinase family. While present in many bacterial...
