P-element transposase that specifically mediates transposition of P-elements. Mediates both; precise and imprecise excision. The THAP-type zinc finger mediates DNA-binding and specifically recognizes sequence elements in a bipartite manner using both the major and minor grooves of its target DNA site. Minor-groove recognition is achieved by a combination of direct base contacts and indirect sequence readout of DNA deformation through a variable, basic loop. By contrast, the adjacent major groove is sequence-specifically recognized by the central beta-sheet of the domain (PubMed:20010837).
